Not a castle at all, but a cliff dwelling dating from the 1100's, this was part of a community of villages plastered against the cliffs in this beautiful green valley. In 1874 the first Euro-American visitors couldn't believe indigenous people could build such sophisticated structures, so in their great wisdom, they attributed it to the Aztecs. Hence the head ringer, Montezuma Castle. These early people had no written language, thus were named by outsiders, as well. The name Sinagua (without water), is however, very fitting.
