This small, frontier, adobe church has a fantastically carved and painted reredos (altar screen) and is built on the site where, believers say, a mysterious light came from the ground on Good Friday in 1810 and where a large wooden crucifix was found beneath the earth. The chapel sits above a sacred pozito (a small hole), the dirt from which is believed to have miraculous healing properties. Dozens of abandoned crutches and braces placed in the anteroom—along with many notes, letters, and photos—testify to this. The Santuario draws a steady stream of worshippers year-round—Chimayó is considered the Lourdes of the Southwest. During Holy Week as many as 50,000 pilgrims come here. The shrine is a National Historic Landmark. It's surrounded by small adobe shops selling every kind of religious curio imaginable and some very fine traditional Hispanic work from local artists.
