On our third day in Havana, we took a taxi to the Christopher Columbus Cemetery, were given a short tour of the major mausoleums, and turned loose for the morning. Not getting lost was a major challenge.
The predominant colour in Cementerio de Cristobal Colón is white. But doors on crypts, gates and details are made of iron, and that iron has rusted.
This detail, seen on a lot of the newer gravesites, has not rusted but I couldn’t figure out what it was made of.
