San Acacio Mission Church (Capilla de Viejo San Acacio) – Built early in the 1860s, the Mission of San Acacio is the oldest standing church in Colorado. Constructed with 24-inch adobe walls, the mission underwent extensive restoration during the 1990s. In addition to stabilizing the foundation, several wooden columns were added to the interior to take the weight of the roof off the fragile walls. An altar screen, or retablo, was commissioned from Maria Romero Cash, a New Mexican artist specializing in religious folk art.
