Fodor's Expert Review La Merced
The church may be overshadowed by the more famous Catedral and Iglesia de la Compañía, but La Merced contains one of the city's most priceless treasures—the Custodia, a solid gold container for Communion wafers more than a meter high and encrusted with thousands of precious stones. Rebuilt in the 17th century, this monastery, with two stories of portals and a colonial fountain, gardens, and benches, has a spectacular series of murals that depict the life of the founder of the Mercedarian order, St. Peter of Nolasco. A small museum is found to the side of the church.
