Circa 1200-1300 AD
This cliff dwelling includes the tallest standing architecture in Mesa Verde, a four-story, 27-foot (8 m) tall structure that was part of an even larger building complex. Although the site has been stabilized by archeologists, 90% is original. Painted murals and pecked rock art are found throughout. https://www.southwestdiscovered.com/square-tower-house-mesa-verde-national-park/
