I took a wrong turn while going to El Cobre in eastern Cuba and wound up stopping an a restaurant perched on a hill. It was a sweltering hot day. I bought a bottle of water and went outside to look at the view.
I could see Santiago de Cuba in the distance. Then I looked down below and noticed there was a prison.
Residents told me it's called Boniato prison. A high-resolution photo of the facility is above, and a lower resolution photo below.
