Native American ruins are remnants of ancient structures built by Indigenous peoples in North America. These sites often include dwellings, ceremonial buildings, and agricultural features, showcasing the rich history and culture of various tribes. Examples include the cliff dwellings of the Ancestral Puebloans in the Southwest and the earthen mounds created by the Mississippian culture. Many of these ruins are protected as archaeological sites and are important for understanding the lifestyles, beliefs, and technologies of Native American societies. Preservation efforts help maintain these sites for future generations, allowing people to learn about the diverse histories of Native American communities.
