If you've come across to see Regla's church, you should also check out this important museum. Spread over two sites, one adjacent to the church and the other (better half) a few blocks up the main street from the ferry, it records Regla's history and Afro-Cuban religions. Don't miss the Palo Monte ngangas (cauldrons) and the masked Abakuá dancing figurines.
There's also an interesting, small exhibit on Remigio Herrero, first babalawo (priest) of Regla, and a bizarre statue of Napoleon with his nose missing. Price of admission includes both museum outposts and the Colina Lenin exhibit.
