This place is the inaccurately named “Montezuma Castle,” built circa 700 AD by the Sinagua people (also not the correct name – sin agua means without water and was the name given to them by the Spanish). It lies south of Sedona in Arizona. More on the site here. It has been a strange week, seeing Frank Lloyd Wright’s Taliesin West and Paolo Soleri’s Arcosanti and then feeling so much more for this little place.
Interesting fact: the U.S. federal monument service was part of Roosevelt’s New Deal, and this site was one of four chosen for preservation when the program was announced.
