Mexico City could have an entire collection of strange facts and curiosities. Here is one. Sinking buildings are a curious phenomenon occurring in Mexico City affecting mainly Hispanic churches.
The ground is slowly giving up as most of these buildings were erected on an already built up Aztec city.
The Aztec’s legacy people of today dare to suggest the phenomenon to be a silent vengeful curse…
The city is sinking on a daily basis, so far it has gone down of about 10 metres in the last few decades.
One theory explains that underneath the city is located the aqueduct which sustains the thirst of over 9 million people. As millions of people drink its water, it slowly becomes less sustaintable and more prone to degradation and debilitation of the structure.
Another explanation dates back from the Aztecs and the Spanish arrival: during the Aztec period when the city was known as Tenochtitlan, the town was initially built on a Lake Texcoco by creating islands using dumped soil right into the lagoon. When the Spanish arrived they erected a second city on top of the Aztec ruins after been demolished. A city atop of another, basically.
The base, however, was a lake. Drained and all, but still a lake.
This has caused buildings to lean and sink into the ground at a rate of up to one foot a year in the most extreme places.
And last, a balcony that has suffered from unevenness of the ground and shows a wavy effect as a result of the ground’s debilitation.
