Iglesia y Convento de Nuestra Señora de la Merced Habana Vieja

Bizarrely overlooked by the tourist hordes, this baroque church in its own small square has Havana's most sumptuous ecclesiastical interior, as yet only partially restored. Beautiful gilded altars, frescoed vaults and a number of valuable old paintings create a sacrosanct mood. There's a quiet cloister adjacent.
