現在的墨西哥城是古代阿茲台克皇朝的首都，該古城在西班牙佔領後被完全摧毀，所以現在的墨西哥城再也找不到阿茲台克人的痕跡，餘下的只是殖民地色彩的建築物。
.
唯一能證明阿茲台克人存在過的證據，大概只有墨西哥城下沉的現象。資料顯示，在過去的150年裏，墨西哥城累計下沉了14米。這主要的原因是因為阿茲台克人在一個大型湖泊上建造了這個城市，由於西班牙政府在殖民時期抽空了湖水，干擾原住民的水利系統，導致墨西哥城地下中空；而墨西哥城對水的要求甚高，降雨量又不足以填補所抽出的地下水；混亂的城巿規劃及城巿發展導至減少樹木等的原因都加劇了墨西哥城下沉的問題。由於這種下沉並不平均，因此，走在墨西哥城，你不難發現建築物都是斜斜的。

墨西哥城因位於海拔高的地方，所以氣溫較低，我在去年七月尾時到訪，氣溫約15-18度左右，大家前往時要帶備合適的衣服啊!

Mexico City is now the capital of the ancient Aztec Empire, which was completely destroyed after the Spanish conquest. Now, there are no traces of Aztecs in Mexico City as it is surrounded by colonial buildings.
.
The only evidence of the existence of the Aztecs maybe on the fact that the city is sinking. Statistic shows that in the past 150 years, Mexico City has sunk 14 meters in total. The main reason is that the Aztecs built the city on a large lake. As the Spanish government drained the lake water during the colonial period and interfered with the water supply system, it caused Mexico City's underground to be hollow. Combing with the high demand of water, insufficient rainfall to refill the groundwater; the chaotic urban planning and the reduction of trees, etc., which have exacerbated the problem of sinking in Mexico City. Since the sinking is uneven, it is not difficult to find that the buildings are all slanted everywhere in Mexico City.

Mexico City is located at a place with high altitude, so the temperature is low. I visited at the end of July last year. The temperature is about 15-18 degrees. Everyone should bring warmer clothes when travel!
