While not ornate, the church's interior boasts bright, colorful decorations. Tourists can see the elegant main altar (dedicated to Mary, mother of Jesus) and gilded pillars with elaborate carvings. Vines of blue and white blossoms often adorn parts of the vaulted ceiling around various holidays. Dec. 8 marks the Festival of Our Lady of the Immaculate Conception, a major holiday at this church. Swing by to see it decked out in tons of colorful lights.
