A small Catholic church in the San Luis Valley is building a monumental project: A giant labyrinth made from adobe to encourage prayer and honor the region's unique heritage. Our Lady of Guadalupe is the oldest parish in Colorado. It's in Conejos, near Antonito. Alfonso Abeyta is a member of the church board. Ronald Rael designed the labyrinth. He grew up in the San Luis Valley and teaches architecture at the University of California- Berkeley.
