The sugar-white Iglesia San Pedro is a delightful little colonial church built with indigenous or artisanal materials – chunky adobe walls and roof, a ceiling made from cardón (cactus wood) resembling shriveled tire tracks and, in lieu of nails, hefty leather straps. The church dates from the 17th century, though its present walls were built in 1745, and the bell tower was added in 1890.
