The Iglesia de Nuestra Señora de la Merced , dating from 1748, is, arguably, Camagüey’s most impressive colonial church with a history imbued with legend. Local myth tells of a miraculous figure that floated from the watery depths here in 1601 and it has been a spot of worship ever since. The active convent in the attached cloister is distinguished by its two-level arched interior, spooky catacombs (where church faithful were buried until 1814) and the dazzling Santo Sepulcro, a solid-silver coffin.
