Ayacucho

Across from the Iglesia Merced, one block from the Plaza de Armas, you'll see the colonial-style Casa Ruiz de Ochoa. The intricate, 18th-century doorway mixes European and indigenous techniques in a style known as Mestizo. Climb up to the second floor for a bird's-eye view of the cobbled patio.
