If you really want to get the feel of colonial Catholicism, visit this church. Better yet, attend Mass here. You won't be disappointed. Built in 1610, the church has massive adobe walls, high windows, an elegant altar screen (erected in 1798), and a 780-pound San José bell (now found inside), which was cast in Spain in 1356. If that doesn't impress you, perhaps the buffalo-hide and deerskin Bible paintings used in 1630 by Franciscan missionaries to teach the Native Americans will. Anthropologists have excavated near the altar, down to the original floor that some claim to be part of a 12th-century pueblo. A small store just off the sanctuary sells religious articles.
