Iglesia de la Merced
The Iglesia de la Merced is in the former La Merced convent. Begun around 1545, it remains the city’s oldest church. It’s a lovely whitewashed building in the Spanish colonial style, with a long, narrow nave, and humble wood and stucco construction. Inside, a heavily gilded baroque high altar is topped by the Virgen de las Mercedes, the patron saint of the city.
