The Native American cultures known for building connected stone homes are primarily the Ancestral Puebloans, also known as the Anasazi. They inhabited the Four Corners region of the United States (where the states of Arizona, Colorado, New Mexico, and Utah meet) and are well-known for their impressive stone dwellings, such as those found at cliff dwellings like Mesa Verde and multi-story structures at Chaco Canyon.
These homes often contained multiple rooms and were constructed from locally sourced materials, including stone, adobe, and wood. The architectural style reflected their adaptation to the environment and social organization.
