... But There May Be a Problem ...

All these interesting buildings are potentially threatened by one thing: Mexico City is sinking into the mire.

The city is built on what was, in Aztec days, a large shallow lake. Most of it has dried up, except for the Xochimilco canals in the far south, now polluted and used mainly for tourist boat rides:


But while the water may be gone, it left behind soft, mucky soil into which buildings are now sinking. All over you see things that look a little bit askew, like these churches whose steeples seem to be leaning into each other:

This has been a problem for many years, but if anyone has come up with an answer, I haven't heard about it yet. Very sad, and a bit scary for the people there.
