无论是身处学校还是步入社会，大家都尝试过写作吧，借助写作也可以提高我们的语言组织能力。那么我们该如何写一篇较为完美的范文呢？下面是小编帮大家整理的优质范文，仅供参考，大家一起来看看吧。

北京天坛导游词500字篇一

它是一座建筑艺术价值非常高的殿宇，总体呈圆形，下边是高2.85米的圆形须弥座，为青白石筑成，有东南西三个方向的出陛，也就是台阶，而在南向出陛还有二龙戏珠的丹陛石。上边是蓝色筒瓦单檐攒尖鎏金宝顶。而在殿内还有八根檐柱和八根金柱，大殿上架没有横梁承托，全都是靠各类斗拱层层上叠来支撑，步步收缩，从而形成了精美的穹隆圆顶。这里边还运用了物理学中的杠杆原理。这组建筑不仅十分精美，而且还有回音壁和三音石，这和刚才我们说的天心石合称天坛三大声学现象。回音壁就是皇穹宇的外墙，围墙建造的磨砖对缝，十分的平滑，是很好的声音载体，可以传声，在传递途中对声音损失极小，只要对着墙说话，就算相隔四五十米，见不到面，都可以清晰的听到对方说话。而三音石则是皇穹宇大殿正前方的三块石头，您站在第一块石头上拍手可以听到一次回音，第二块石头可以听到两次，而第三块就可以听到三次回音，所以称为三音石。在后来也有人把它叫做三才石，取天地人三才的意思。

也许您刚才就已经注意到了，天坛有非常多的柏树，不错，它就好像北京一个天然的氧吧。而在这许多古柏当中，有一株500余岁的桧柏，就是回音壁西墙外的这棵九龙柏。它的树干纹理非常的奇特，布满了沟壑，而且旋转扭曲，好像9条蟠龙缠绕嬉戏，所以叫它九龙柏真是一点也不过分。

在游览过了圜丘坛和皇穹宇之后，我们就即将走进祈谷坛了，而现在我们脚下连接两个祭坛的就是丹陛桥，也叫做海墁大道，而它也是皇帝登上祈谷坛的唯一通道，长360米，桥面上分为三条道，中间的是神道，东边是御道，西边的就是王道。而它作为通道为什么又要称为桥呢?这有两种说法，一种是说路面南低北高，步步高升，好像与天相连接的桥;而另一种就是说路面下边建有进牲门，类似立交桥，所以称之为桥。说到进牲门，就是在祭祀前，牛羊都要通过桥下的一个券门被赶到500米外的宰牲亭宰杀，制成供品，所以这个通道也被叫做鬼门关，因为一进去就有死无生了。

好，回到正题，现在呈现在您面前的就是祈谷坛的完整建筑群。前面的这个石台是具服台，在每年孟春祈谷祭祀之前，皇帝照例还是要来到这里搭建幄次，盥洗更衣，所以这里还有小金殿之称。

到此，祈谷坛的主体建筑祈年殿就出现在我们面前了。祈年殿下的基座是三层的圆形石台，而在正面三层石台阶中，分别装饰着巨大的浮雕，叫做殿前丹陛石雕。从下之上内容分别是：瑞云山海，双凤山海，双龙山海。各层排水孔的图案和浮雕的内容也是对应的。东西两旁的配殿个有九间，原来是安放从祀牌位的地方，不过在家靖年间，把它们挪到了先农坛，所以现在这里也就没有什么实际用途了。而祈年殿本身就是一座极具中国特色的独特建筑。圆形三重檐攒尖屋顶向上层层收缩，都是用蓝色的琉璃瓦覆盖，以此来象征天。顶部是鎏金宝顶，抬头仰视，便是龙凤藻井，中心是龙凤成祥的图案。而巨大的三层殿顶就是靠殿内的28根落地柱支撑的，中间的四柱名叫龙井柱，东南西北方向分别代表了春夏秋冬;而龙井柱外围的12个红漆金柱所分割出来的12个开间，则分别代表了一年的12个月份;外面两环的24个开间有分别代表了一年的24个节气;同时，这28根大柱，也代表了天上的28个星宿。据说这祈年殿是仿照古代明堂设计建造的。在感叹殿内建筑的同时，也让我们把注意力逐渐转移到殿内的陈设上来。这里的陈设是按照清朝咸丰年间原状恢复的，正面的雕龙宝座上供奉着的是满汉合璧的皇天上帝神版，左右两侧的石台上供奉的是清朝前八位皇帝的牌位。

和每年的祭天一样，这里是用来祈谷的地方。在祭祀的当天，有乐队在殿外月台上奏乐，身穿祭服的皇帝虔诚步入神殿，向牌位行大礼，祈祷上苍，然后把供品送到祈年门外东边的燔柴炉和燎炉焚烧，送上天宫。祈谷礼节和祭天的差不多。

到这里，祈年殿也差不多讲完了，而它还有一个附属建筑，作用和皇穹宇差不多，也是存放祈谷坛祭祀神主的地方，就是祈年殿北侧的皇乾殿。

现在我们从祈谷坛的东门出来，可以看到一条连檐通脊的长廊，共有七十二间，俗称七十二连房，它不仅用来连接神厨神库，而且也是祭祀时运送祭品的通道，在长廊的东头，就是宰牲亭，就是前面所说过了鬼门关的牲畜要道这里来屠宰。而在长廊的东南方向，有八块巨大的青石，称为七星石，都是风水镇石。可是这里命名有八块石头为什么叫七星呢?原来明代在这里放的的确是七块石头，而最小的那一块则是清代增添上的。关于七星石的说法每个朝代都不同。在明代，有个道士和皇帝说祈年殿的方位不好，不利于国家，所以就在这里放了象征着北斗七星的七块石头。而在清代，康熙皇帝为了给满族爱新觉罗氏寻找从东北如主中原的理论依据，就派人考察山脉，发现泰山是长白山的余脉，所以就在原来七块石头的东北方有放了一小块儿青石，象征东北长白山，如果按这种说法，那八块石头就应该叫做七峰东岳。暂且不管他们怎么定论了。今天的观光游览就要结束了，在天坛的这段时光希望能成为您北京之游中的永恒记忆。同时也请您把天坛的祝福带给您的家人朋友。

北京天坛导游词500字篇二

ladies and gentlemen:

welcome to the temple of heaven. (after self-introduction) preserved cultural heritages of china. there are basically two kinds of visitors who come here: local pensioners who do exercises here in the morning and evening and sightseers both from home and abroad. all in all ，there are 12 million visitors very year. now we are going to go along the route that leads to the alter. it will take roughly one hour. mind you ，the emperor also walked along this route to pay tribute to the god of heaven.

the largest group of architectures ever to be dedicated to heaven ，the temple of heaven served as an exclusive altar for chinese monarchs during the ming and qing dynasties. it was decreed that rulers of successive dynasties would place altars in their own capitals to worship heaven and pray for good harvest. but why ?

the ancient chinese believed that heaven was the supreme ruler of the universe and the fate of mankind，and thus worshiping rites dedicated to heaven came into being.

the heaven the ancient chinese referred to was actually the universe， or nature. in those days， there were specfic rites of worship. this was especially true during the ming and qing dynasties when elaborate ceremonies were held.

the temple of heaven was built in 1420 during the reign of emperor youngle of the ming dynasty. situated in the southern part of the city ，this grand set of structures covers an area of 273 hectares. to better symbolize heaven and earth ，the northern part of the temple is circular while the southern part is square .the whole compound is enclosed by two walls， a square wall outside a round one. the outer area is characterized by suburban scenery， while the inner part is used for sacrifices. the inner enclosure consists of the hall of prayer for good harvest and the circular mound altar.

the circular mound altar is enclosed by two walls ，each containing four groups of southern lattice star gate， each in turn consisting of three doors， with 24 marble doors altogether. standing on the passage facing north， you will notice that with each pair of doors on is narrower than the other. this reflects the feudal hierarchy: the wider door was reserved for monarchs， while the narrower one was used by courtiers.

on the day of the ceremony ，the emperor would don his ritual costume and be ushered in by the official in charge of religious affairs. he ascended the three terraces in the forefront to pay tribute at the alter.

we are now on the top terrace of the altar， or the third terrace .each terrace has a flight of 9 steps. at the center of this terrace lies a round stone surrounded by 9 steps. at the center of this terrace lies a round stone surrounded by 9 concentric rings of stone. the number of stones in the first ring is 9， in the second ，18， up to 81 in the 9th ring. even the number of carved balustrades on these terraces is a multiplee of 9. but why?

according to ancient chinese philosophy， yin and yang were two opposing factors. heaven and the odd numbers belonged to yang while the earth and even numbers belonged to yin. nine was the largest heavenly number accessible to man . what is more， the ancient people also believed that heaven consisted of nine layers and that the emperor` s abode was on the uppermost tier.

once more look at the round stone in the center. the upper terrace is nine zhang (a chinese unit of length， one zhang equals 3.3 meters ) in circumference ，while the middle is 15 zhang， the lower，21 zhang. classified as yang numbers， the sum of these numerals is 45 zhang which was meant to symbolized success. what is more， by applying the concept of odd numbers and strengthening nine and its multiples， the concept of heaven was thus illustrated and realized . the concept of nine will also be mentioned when we visit some other buildings.

now i will give you a brief account of what happened here annually on the inter solstice. the memorial tablet dedicated to heaven would be set up on the north side of the terrace， while tablets dedicated to the emperor `s ancestors would be enshrined on the flanks. the service would begin around 4 o` clock in the morning. all of the lanterns would be lit .in the foreground， a sacrificial calf is being barbecued. on the square in front of the altar， the emperor， under heavy escort of nearly a thousand courtiers， princes of royal blood ，musicians， dancers and uniformed soldiers， would slowly ascend the altar to offer sacrifice and pray in honor of heaven. when the service drew to a close ，the sacrifice offered in front of the memorial tablets would be incinerated .all of participants would watch the thick smoke rise upward as if they were seeing god off .music and dancing would follow .in the end ，the emperor would return to the forbidden city secure in the belief that he would be blessed and protected by heaven until the next winter solstice.

it is interesting to note that ，the stone in the very middle of the altar was of major importance ，since it was where the emperor used to stand to say his prayer. the stone ，which is known as the god`s heart stone， is peculiar in that it is characterized by a specific acoustic phenomenon: it made the emperor` s voice clearer and louder， thus adding to the mystic atmosphere of the service .you can try this out by yourself. (proceed northward to pass through the lattice stargate)

this structure is known as heaven` s storehouse. it is entered through the gate of glazed tiles. the roofing，beams， and brackets are all made of glazed tiles or bricks. this is the only structure of its kind in china today .

the heaven` s storehouse was where memorial tablets dedicated to the gods were kept. douglas hurd， a former british foreigh secretary ，once said ， “god attends to his affairs on the cir4cular mound altar but stays here. ” now let` s go in to to see it (go through the left side door)

(in the courtyard of heaven` s storehouse)this is the imperial vault of heaven， the main structure of heaven` s storehouse. it was built in 1530 and is 17 meters in height and 19 meters in diameter. the structure feature blue roofs topped by a gilded ball ，and carved wooden doors and windows. it is decorated with colored paintings. founded on a 3-meter-hign round marble terrace ，the building also features a gigantic carved marble ramp laid in the stone staircase leading up to the front entrance.. the ramp is carved in “two dragons playing with a pearl ” design in relief. we will enter the main hall by going up the stone staircase on the eastern side.

the arch of the hall is buttressed by 16 giant pillars on two rings. on top of the pillars there are gilt brackets supporting a circular caisson ，or covered ceiling .the ceiling is characterized by a golden coiling dragon design. the 8 pillar of the inner ring are painted scarlet and decorated with golden lotuses.

to the north of the hall there is a marble pedestal. atop it ，up a wooden flight of 9 steps， is where the major tablet dedicate to heaven was enshrined. on each flank four tablets are enshrined in honor of the ancestors of the qing emperors. in the annex hall in hornor of the ancestors of the qing emperors. in the annex halls in the courtyard， there are tablets dedicated to the deities of the sun， moon ，constellation， cloud ，rain， wind and thunder.

aside from exquisitely laid out architectures， heaven` s storehouse is also famous for two structures with peculiar acoustic features， i. e. the echo wall and the triple- sound stone. a mere whisper at any point close to the wall can be heard clearly on the other side， although the parties may be 40 or 50 meters apart. this is possible because the wall is round and hermetically constructed with smooth ，solid bricks.

in front of the steps leading away from the halls is the triple sound stone. if you stand on the first stone and call out or clap your hands， the sound will echo once; on the second stone， the sound will be heard twice; and on the third stone， the sound will repeat three times. hence the name. (go out through the right door and stroll along the circular path nor thward)

the temple of heaven is also famous for its cypress trees-there are more than 60，000 cypress trees in all，among which over 4，000 are more than one hundred years old ，adding to the solemn atmosphere of the temple .this tall cypress was planted more than 500 years ago. its thick branches and twisting trunk resembling nine coiling playful dragons; thus it is known as the nine-dragon cypress. it is said that this tree was here to welcome the monarchs. now it is here to welcome visitor from all over the world.

now we are back again on the central axis. this brick-arched gate is known as chengzhen (adopting fidelity) .this gate is the northern gate of the circular mound altar and the hall of prayer for good harvest. the hall of prayer for good harvest is situated at the extreme end of the axis. it was used by the emperor in the first month of every lunar year for services dedicated to good harvest.

entering the hall of prayer for good harvest， we set foot on a raised passage 360 meters long， which the emperor also took to proceed to the hall. this broad north-south walkway， called danbiqiao (red stairway bridge)， connects the two sets of main building in the temple of heaven and constitutes a single axis.

the passage is spanided into left， control and right paths by the cross arrangement of slabs. the central and the widest path is known as heavenly thoroughfare ， which was reserved exclusively for god; nobody， including the emperor， was allowed to set foot onto it . the emperor used the path on the east，which is known as the imperial walk. the ministers and princes used the one on the west .interesting enough ，there is no walkway left for ordinary people. this is because the temple of heaven used to be off-limits to them.

contrary to appearances， this walkway is not a bridge at all . but how so ? this road is 4 meters above the ground and there is a cavern underneath that was reserved for sacrificial oxen and sheep. the cattle were slaughtered at a slaughterhouse about 500 meters away and brought here for sacrifice. all in all ，it can be said this walkway did serve as bridge and can be looked upon as the first cloverleaf in beijing.

looking back at the thoroughfare， you may realize that this walk is gaining height toward its northern end. as people approach the architectural group of the hall of prayer for good harvest， the flanking groves of cypress recede and perspective widens. here you are in heaven.

the marble terrace up ahead is called jufutai， or costumechanging terrace. it is located to the east of the red stairway bridge and covers a space of 25 square meters .it has marble slab balustrades. the day before the service ，officials in charge would put up a yellow satin tent on the terrace for the emperor to change out of his yellow dragon robe into blue ceremonial clothes. after the service，the emperor would return to the tentand change back into his imperial robe before returning to the palace. (proceed to the south gate of the hall of prayer for good harvest)

this structure is called the gate of pray for good harvest. we can catch a slight glimpse of the central building ，the hall of prayer for good harvest， though the colonnade of the gate. a gigantic and lofty group of buildings， the complex includes the gate of prayer for good harvest， the hall of prayer for good harvest， eastern and western annex halls ，the huanqian (imperial heaven) long corridor， heaven kitchen， slaughterhouse， etc.

the annex halls were symmetrically built on a 1.5-meter-hignbrick-and-marble terrace ，to set off the loftiness and magnificence of the main hall .this unique building ，38 meters in height， is characterized by a cone-shaped structure with triple eaves and a top that is crowned by a gilt ball. the roofing is made of blue glazed tiles， the color of the sky .underneath the roof， the beams and bracket are decorated with colored paintings. the base of the structure is a triple-tiered， circular marble terrace. at a distance， the terrace looks like a gigantic， spiraling cloud with the structure perched on top of it .

today the hall of prayer for good harvest is the hallmark of beijing， which enjoys a prolonged history of civilization.

the base of the hall is a triple-tiered， circular marble terrace， which is 90 meters in diameter and 6 meters in height ，covering a space of 4，000 square meters. meticulous accuracy was given to the layout of the structure. in the middle of each three-tiered flight of stairs， there is a giant marble ramp carved in cloud， dragon and phoenix designs. to set off the ramps， the top of the balustrades and downpipes are designed with corresponding floral scrolls. in southern part of each tier， a gigantic bronze incense burner is placed. sandalwood was burnt in them when rites were observed.

(in front of the hall of prayer for good harvest) climbing up this marble terrace， we see the main hall，a masterpiece of ancient china. looking up you will see the caisson， or covered ceiling， characterized by complex designs of dragons and phoenixes. in and out ， the hall is decorated with colored drawing of dragons and phoenixes.

without the use of steel ，cement and nail， and even without the use of big beams and crossbeams，the entire structure is supported by 28 massive wooden pillars and number of bars， laths， joints and rafters. the four central pillars， called the dragon-well pillars， are 19.2 meters high and painted with designs of composite followers， representing the four season. there are two rings of 12 scarlet pillars each. the inner ring represents the 12 months and the outer rings the 12 spanisions of the day and night .between the two rings there are 24 partitioned spaces to mark the solar terms of the chinese lunar year. the pillars， 28 in number， also represent the 28 constellations in the universe- the ancient chinese believed that there were 28 constellations that made up the sky.

the center of the stone-paved floor is a round marble slab， which is 88.5 centimeters in diameter. interestingly， the slab features natural black and white veins， corresponding to the dragon-phoenix design on the ceiling. this particular slab is known as the dragon-phoenix stone and is regarded as a treasure inseparable from the hall.

the furnishings within the hall are placed in their original positions dating back to when emperor xianfeng ruled .in the forefront and above the throne are enshrined tablets in commemoration of heaven. on either table on each side tablets of the emperor` s ancestors were placed. each tablet is fronted by an altar. a total of 24 kinds of offering were made on it ，including soup， wine， assorted cereals， and a calf.

the sacrificial rites were observed in the wee hours of the morning， sometime in the first month of the chinese lunar year. because it was still dark， candles， lanterns and torches were lit. this lighting coupled with the incense being burnt inside the hall ，helped make the ceremony both grand and mystical.

by the time the service began，207 musicians and dancers would be performing on platforms outside the hall. the emperor， in his blue sacrificial robe and with an air of piety and sincerity， would walk slowly into the hall， kowtow， and offer wine and prayer in hornor of the deities and his ancestors. all of the offerings would then be taken to incinerators on the eastern side of the gate of prayer for good harvest. with this we conclude our visit to the temper of heaven. the feudal monarchs and their sacrificial rites have long vanished in history .however， this group of magnificent and lofty structures remain as a fine testament of the ancient chinese` s ingenuity and as one of the cultural heritages of mankind.

from the eastern gate of the hall of prayer for good harvest， we have now enter a 300-meter-long corridor. consisting of 72 sections， this corridor served as a connecting building between the slaughterhouse. heaven kitchen， and the main hall ，it is said that this once served as a sacrificial food production line. flanking the corridor are shopping stalls. you may find some souvenirs for your family and friend there.

well ，that is all for this tour. thank you for your attention. i look forward to your next visit. good luck and bon voyage.

北京天坛导游词500字篇三

各位游客，你们好!今天我们要参观的是以前皇帝祭天的地方——天坛。

天坛是明朝永乐皇帝建成的祭天圣坛，主建筑是大祀殿，也就是今天的祈年殿。天坛有外坛墙和内坛墙，北圆南方，寓意天圆地方。乾隆年间，将大祀殿改为现在的祈年殿，将屋顶瓦片改成蓝色的琉璃瓦，形成了今天我们看到的这个世界上最大的祭天建筑群。

这一祭天圣地，在1860年遭到了英法联军的洗劫，1900年又遭到八国联军的蹂躏。新中国成立以后，这里成了著名的旅游景点，来这里的除了旅游者，还有很多健身的人们。

现在就让我们沿着当年皇帝登坛的路线开始游览。

现在我们是沿着天坛建筑的中轴线在向南行进，将要看到的就是古代皇帝祭天的圜丘坛。圜丘有两道围护墙，外方内圆，符合天圆地方的说法。每道墙都有四组门，大家可以注意到，门的大小都不一样，这是因为中门是上帝专用的，所以高大;皇帝只能从左侧的门进入;而其他的官员只能从右边最小的门通过。

来到圜丘坛下，我们马上要开始登坛了，不过要请您留心数一数，每层坛面都有多少台阶。到了最高层，大家会发现，坛上所有的台阶数，都是九或者九的倍数。这些难道都是巧合么?当然不是，因为古人认为九是极阳数，所以工匠们便用这个数字来赋予圜丘坛“崇高”之意。

说完了神坛的奇妙，我再给您介绍一下祭天大典的盛况。

到了每年的冬至，皇帝就要在这里祭天。在这个典礼上，需要特别提到的是皇帝恭读祝文所站立的地方，就是这块天心石。它是天坛三大声学现象之一。在这里朗读的时候声音特别洪亮，各位游客不妨体验一下，也像当年的皇帝一样，向上天诉说自己美好的愿望。

现在咱们继续沿着中轴线行走，面前的建筑叫做天库，它的正殿就是皇穹宇。皇穹宇三个字也分别代表了“至高无上”“天”“宇宙”的意思，更加显示出它的神圣和至尊。这组建筑不仅十分精美，而且还有回音壁和三音石，这和刚才我们说的“天心石”合称天坛三大声学现象。

北京天坛导游词500字篇四

各位团友大家好，今天我们要参观的是世界上现存规模最大、保存最完整的古代祭天建筑群——天坛。

天坛位于北京东南侧，也是我国和世界上现存规模最大的古代祭祀性建筑群。始建于明永乐四年，至明永乐十八年完工。占地面积273公顷。相当于故宫的三倍还多。是明清两代皇帝祭天祈谷的场所，每年“三孟”举行祭祝，即孟春祈谷，孟夏祈雨，孟冬祀天。初建时这里也是祭祀地神的地方，称天地坛。直到明嘉靖九年在北部另建地坛。那时天地开始分别祭祀，同时还另建两坛。才形成了现今的南天坛、北地坛、东日坛、西月坛这“京郊四坛”。

天坛是圜丘、祈谷两坛的总称。建筑布局呈“回”字形，有坛墙两重，形成内外坛，坛墙南方北圆，象征天圆地方，故又称天地墙。主要建筑有祈年殿、圜丘坛、皇穹宇、斋宫、外坛神乐署和牺牲所。除了斋宫在西部以外，其他主要三组均在一条中轴线上。在北京古代建筑中是唯一一个中轴不对称的建筑。

可是这样一个祭天圣地，却也曾经在1860年时遭到英法联军的洗劫，继而在1900年的时候又遭到了八国联军的蹂躏。在1916年袁世凯登基的时候也曾经在天坛上演了一出祭天的闹剧。在1918年，天坛最终还是以公园开放。解放以后天坛不仅成了著名的旅游景点，而且还是北京城市绿地的组成部分，来这里的不光是旅游者，还不乏一些专门为了强身健体的老人们。

现在就让我们沿着当年皇帝登坛的路线开始此次游览。

我们先介绍一下斋宫。斋宫位于天坛西门内，里面有著名的无梁殿。面积约4万平方米，有小紫禁城之称，是皇帝祭祀前斋戒的地方。皇帝在祭天前要在此斋戒三天。三天里“不吃荤、不饮酒、不娱乐、多沐浴、不理刑名、不近女色。”所谓至斋。在斋宫殿前的露台上左右还各有一个石亭。右面的为时辰亭，左面的为斋戒铜人亭。铜人高0.5米身着文官服饰，相传是唐代的魏征。手持斋戒铜牌，上刻“斋戒”二字，用来警示皇上。

下面我们来看圜丘坛。圜丘坛通高5.7米，分三层。每层的四个方向各有九级艾叶青石铺就的台阶。四面围有汉白玉护栏。坛外面有两道围墙，围墙从东向面依次有泰元、昭亨、广利、成贞四座棂星门。现在我们开始登坛，请大家注意一下坛面。坛面上所用的石料的数字都与九相关，上层直径9丈，中层直径15丈，下层直径21丈。三层共45丈，既是9 的倍数又含有“__之尊”的意思。最上一层坛面中间的那块圆形的大理石叫做天心石。又叫“亿兆影从石”。人站在上面说话会感到强烈的共鸣。围绕天心石这一层共砌着9圈巨大的扇形石，第一圈9块，第二圈18块。以此类推，到了最外边的第九圈正好是81块;第二层，第层也一样。直至最外第27圈。同样大家抬头就可以看到的护板被四面台阶分为四个部分，每个部分也都有9块，中层的护板是18块，下层的是27块，这些都是根据阴阳五行来做的。9是极阳数，所以古代的工匠便用这个数字来强调天的崇高，神圣。祭天时的步骤可分为：燔柴迎帝神、苍壁礼天、进俎、初献礼、亚献礼、终献礼、撤馔、送帝神、望燎。

大家再看圜丘坛的西南方。有三座高大的石台，叫做望灯台。台上的长杆是望灯杆。杆高九丈,通体红色。祭天时，望灯杆上各悬挂一只直径六尺高八尺的灯笼。灯笼内点蟠龙通宵宝蜡，可持续燃烧六个时辰。不灭、不流油、不用剪蜡花。

现在咱们继续沿着中轴线行走，前面的建筑就是天库——皇穹宇。皇穹宇建于明嘉靖九年，起初叫做泰神殿，嘉靖十七年，改名为现在的皇穹宇，这里是专门存放神牌的地方。既有皇天上帝的神牌，也有风雷雨电的神牌。这组建筑不仅造型精美，而且还有和天心石合称天坛三大声学现象的回音壁、三音石。

回音壁就是皇穹宇的外墙，围墙建造的磨砖对缝，是很好的传声体，只要正确的对着墙说话，就算相隔四五十米，见不到面，都可以清晰的听到对方说话。而三音石则是皇穹宇大殿正前方的三块石头，您站在第一块石头上拍手可以听到一次回音，第二块石头可以听到两次，而第三块就可以听到三次回音，所以叫三音石。后来取天地人三才之意又叫“三才石”。

大家应该早就注意到了吧!天坛有非常多的柏树。而在这许多古柏当中，有一株500余岁的桧柏，就是回音壁西墙外的那棵九龙柏。因为它的树干表面布满了旋转扭曲的沟纹，犹如九龙飞腾，所以叫它九龙柏。

回音壁北侧，有一条宽广的大道，也就是叫做海墁大道的丹陛桥。因路面下边建有涵洞成立体交叉，类似立交桥，所以称之为桥。穿过丹陛桥后，我们看到的就是祈谷坛建筑群了。祈谷坛是三层汉白玉圆坛，占地面积近六千平方米。祈年殿就建上面。

祈年殿是天坛的象征。也曾经是中国的象征性建筑物，原名大祀殿。有祈祷丰收之年的意思。在建筑上，它是圆形重檐攒尖顶，顶部覆盖蓝色竹节瓦。逐层收缩，高达九丈，由28根红柱子支撑。是我国唯一留下来的仿明堂式建筑。过去，琉璃瓦分三种颜色，也三种不同的意思。即：上青，代表上天、中黄，代表皇帝、下绿，代表黎民百姓。后为了表示对上天的尊敬，全部改换成蓝色琉璃瓦。

而殿顶和支撑殿顶的28根柱子，也有不同的代表意义。殿顶周长30丈，代表一月30天。四根龙井柱，象征一年有四个季节。中层12根象征一年有12个月。外层12根象征一日有12时辰。中层与外层24根象征24节气。三层共28根象征天上的28星宿。如果再加上殿顶顶部的8根童柱共计36根。则象征天上的36天罡。在宝顶上还有一根叫雷公柱的镏金短铜柱，象征皇帝一统天下。除此之外，殿顶内部还有一“龙凤藻井”，地面有一块“龙凤呈祥石”。二者相映成趣。

和祭天一样，每年这里都要举行用来祈谷的礼仪。每次祭祀前都要将大殿修饰一新。

现在我们从祈谷坛的东门出来，可以看到一条长廊，共七十二间，俗称七十二连房，它连接神厨神库，是祭祀时运送祭品的通道。在长廊的东南方向，有八块巨大的青石，称为七星石。这是风水镇石。关于七星石的说法有二。一说明代有个道士和皇帝说祈年殿的东南方空旷，于国家不利。所以就在这里放了象征着北斗七星的七块石头。二说，七星石代表东岳七峰。至于东北的小青石，是因为康熙皇帝为了给满族入主中原寻找理论依据，而派人考察泰山的发脉地络，认定泰山发脉于东北的长白山后增加的。

今天的观光游览就要结束了，在天坛的这段时光希望能成为您北京之游中的永恒记忆。
