萬(wàn)里長(zhǎng)城在我國(guó)北方遼闊的土地上,東西橫亙著一道綿延起伏、氣勢(shì)雄偉、長(zhǎng)達(dá)一萬(wàn)多里的長(zhǎng)墻.這就是被視為世界建筑史上一大奇跡的萬(wàn)里長(zhǎng)城.萬(wàn)里長(zhǎng)城是我國(guó)古代一項(xiàng)偉大的防御工程它凝聚著我國(guó)古代人民的堅(jiān)強(qiáng)毅力和高度智慧,體現(xiàn)了我國(guó)古代工程技術(shù)的非凡成就,也顯示了中華民族的悠久歷史.
長(zhǎng)城是中國(guó)也是世界上修建時(shí)間最長(zhǎng)、工程量最大的一項(xiàng)古代防御工程.自公元前 七八世紀(jì)開始,延續(xù)不斷修筑了2000多年,分布于中國(guó)北部和中部的廣大土地上,總計(jì) 長(zhǎng)度達(dá)50000多千米,被稱之為“上下兩千多年,縱橫十萬(wàn)余里”.如此浩大的工程不僅 在中國(guó)就是在世界上,也是絕無(wú)僅有的,因而在幾百年前就與羅馬斗獸場(chǎng)、比薩斜塔等列 為中古世界七大奇跡之一.
準(zhǔn)確地說(shuō),長(zhǎng)城不只有一座.在兩千多年間,各代王朝在中國(guó)的北方修建了許多座長(zhǎng) 城.其中,最"新"的而且也是目前保存最完整的一座建于中國(guó)明代（1368－1644）.
明長(zhǎng)城是一座結(jié)構(gòu)龐大復(fù)雜的邊防堡壘,綿延6700公里.它是世界最偉大的人工奇跡.
明長(zhǎng)城翻山越嶺,蜿蜒迂回于崇山之間.看見(jiàn)它人們不由肅然起敬,感嘆在如此險(xiǎn)峻 的地方使用數(shù)量如此眾多而且巨大的建筑材料.長(zhǎng)城見(jiàn)證了古代中原農(nóng)業(yè)文明和北方游 牧民族間劍拔弩張的激烈對(duì)抗.
明代長(zhǎng)城是人類歷史上耗費(fèi)人力最巨,時(shí)間最久,物資最多的建筑.這使它成為一件 最大的歷史文物.在今天這個(gè)瞬息萬(wàn)變的世界,保護(hù)長(zhǎng)城是文化遺產(chǎn)保護(hù)領(lǐng)域最具挑戰(zhàn)性的任務(wù).
