Mesa Verde, Colorado
This Colorado location is well-known for its archaeological sites. It’s a World Heritage Site besides also being a National Park, making it a rare blend.
Sometime during the late 1190s, after mainly living on the mesa top for over 600 years, many Puebloans began living in villages they built beneath the overhanging cliffs. The houses ranged in size from one-room units to villages of over 150 rooms.
Today these remnants of the past enhance the attractiveness of the cliffs in the surrounding region. There are around six hundred cliff houses, but Cliff Palace is one of the most popular. It is believed to be the largest cliff residence on the entire continent of North America, making it one of the most visited.
