Mexico City was founded on June 8, 1325, and was initially named Mexico-Tenochtitlan.
Mexico City is built on the ruins of an old Aztec city named Tenochtitlan.
The central canal was built in 1900 and runs to the Panuco River.
The city's heaviest buildings are sinking at a rate of 4 to 12 inches per year due to the artisan wells and drainage lowering the water tables, making the ground too weak to hold them.
Mexico City is built in an area of great seismic activity, with extensive earthquake damage caused in 1957 and 1985. Over 30,000 people were left homeless from the earthquake in 1985.
Mexico City's population more than doubled between 1930 and 1950.
Mexico City houses one of the world's longest avenues, Avenida Insurgents.
