The impressive Church of the Immaculate Conception (Iglesia de la Inmaculada Concepción) is a whitewashed stone church built between 1797 and 1804 to replace an adobe temple dating from the early 1700s. Its thick stone walls, small windows, and squat buttresses have kept it intact through two centuries of quakes and tremors. It has a pale interior with marble floors and stained-glass windows, and is flanked by tidy gardens. There are Sunday services at 6 AM, 9 AM, 11 AM, and 6 PM.
