I was taking pictures along the Malecon one day when a taxi driver or somebody, I can't remember who, referred to an apartment building there with a peculiar nickname: The Coffins.
I didn't understand what the guy was talking about until I looked more closely at the building. Sure enough, the windows facing the Malecon are surrounded by what look like little coffins. Some are right side up. Others are upsidedown. At least that's what they look like if you use your imagination.
Here are two photos of the building, one shot from a distance, the other a tighter view. See what I mean about the coffins?
