Built in 1755, this hemmed-in church was reconstructed in the 19th century. Beautiful gilded altars, frescoed vaults and a number of old paintings create a sacrosanct mood; there's a quiet cloister adjacent. Two blocks away is the rather neglected Iglesia Parroquial del Espíritu Santo , Havana's oldest surviving church, built in 1640 and rebuilt in 1674.
