Agua Verde Castle was built by Duane Durham in the 1970's as a family residence. This impressive edifice sits on a hilltop above Agua Verde (green water) Creek, and is easily visible from Interstate 10 and other surrounding areas; this photo was taken from the parking lot at Collossal Cave.
Directions: North of Interstate 10 between exits 281 and 289. Private residence not open to the public; do not disturb the occupants.
Last visited: April 2012.
