Cliff Palace, Colorado
From a distance, Cliff Palace looks like a sprawling, intricate kid’s sandcastle city. Tucked away in a nook beneath the bluffs in Mesa Verde National Park, this Ancestral Puebloan ruin is believed to have been built sometime between 1190 and 1260 AD. It’s also the most significant known cliff dwelling in North America.
The palace’s many rooms and kivas, spaces used by Puebloans for meetings and religious rituals, are carved out of sandstone and held up by wooden beams and mortar. It’s incredibly well-preserved, but unfortunately, tours are only available with the park’s rangers.
