從春秋時(shí)代開始，我國古代人民便已熟悉城墻建造技術(shù)。在從公元前5世紀(jì)至公元前221年的戰(zhàn)國時(shí)期，秦、魏、趙、齊和燕各國建立廣泛的防御工事來保衛(wèi)自己的邊界。公元前221年，秦始皇征服了所有反對國家而統(tǒng)一了個(gè)國，建立秦朝。為了避免匈奴人的入侵，他下沿著整個(gè)國家的北部邊界建立新的城墻，以連接殘留的防御工事。古城墻大部分已侵蝕了數(shù)百年，只有極少數(shù)路段保留至今。后來的長城由漢，隋和晉朝以極大的代價(jià)來修理，改建或是擴(kuò)建長城以捍衛(wèi)自己免于北方的侵略。在15世紀(jì)40-60年代，明朝修建了所謂的“遼東長城”。明朝末年，長城抵御了滿清帝國入侵。然而，當(dāng)山海關(guān)隘口被吳三桂打開后，滿族人迅速占領(lǐng)了北京，建立了清朝。在清朝統(tǒng)治下，中國的邊界一直延伸到長城之外和蒙古，所以建造和維修長城的工事被停止。History從春秋時(shí)代開始，我國古代人民便已熟悉城墻建造技術(shù)。在Notableareas

長城最寬是9.1米（30英尺），顏色和周圍土壤的顏色相似。基于光學(xué)分辨能力，人們從月球上直接用肉眼可以看到直徑70英里（110公里）以上的物體。從月球表面看長城的寬度就好比從2英里外看人類的頭發(fā)一樣。要從月球上看到長城的話將需要優(yōu)于正常視力17,000倍的空間分辨率。因此，月球的宇航員從未聲稱已經(jīng)從月球上看到長城也就不奇怪。Visibilityfromspace月球視野VisibilityfromthemoonTheGreatWallisthemigh
