Marker: "The Mystery of Sun Temple"
Historical marker: "The Mystery of Sun Temple. Sun Temple is a never-ending source of speculation for scholars and visitors alike. It was built sometime in the 1200s, and was part of the community of cliff dwellings that surrounded it. Its D-shaped outline; no evidence of roofing; few doors or household artifacts; and massive architecture is unlike any other structure in the park. Of the few similar D-shaped buildings found in the region, it is the only one not built within a pueblo. Could it have had social, ritual, or even symbolic functions? Some studies suggest it had a role in celestial observation." Sun Temple, Montezuma County, Colorado, USA.
