The Iglesia de Nuestra Señora de las Mercedes, constructed during the first half of the 16th century, was sacked by Drake and his men and reconstructed on numerous occasions following earthquakes and hurricanes. The church is remarkable for its pulpit, which is sustained by a support in the shape of a serpent demon. The intricate baroque altarpiece is carved from tropical hardwood. Of the group of buildings that pay homage to the Virgin Mary, only the cloister adjacent to the church is in original condition.
