No Santería museum can replicate the ethereal spiritual experience of Regla de Ocha (also known as Santería, Cuba's main religion of African origin), though this house has a try with a Santería altar to Yemayá, Goddess of the Sea, laden with myriad offerings of fruit, water and stones.
The house is presided over by santeros (priests of the Afro-Cuban religion Santería), who'll emerge from the back patio and surprise you with some well-rehearsed tourist spiel. On the goddess's anniversary, March 19, ceremonies are performed day and night.
