Coacalco, Mexico

On the left if the corner of the church pictured below. The neighborhood and the housing act almost as a surrounding wall for the church.

This is a small neighborhood parochial school church built in the 1940's. One of few without surrounding walls to provide sanctuary and keep out harm. I assume given it's "small neighborhood" usage, it was never a target like many of the larger churches from the 18th century and later.
