Wall Remnants

This is not damage from our recent storm, rather this is the remains of a wall close to one of our previous homes here in Zihuatanejo. I remember then being drawn to the patterns created by the concrete remnants, but for some reason never got around to photographing it. Today that oversight was remedied, once my wife pointed it out to me once again. The grey area in the lower left is part of the rock the wall once must have covered. No one bothered to remove it, they simply built the wall over it. Maybe that is why this is all that remains of the former wall. I do wonder what was painted on it back then.
