Mound burial refers to the practice of interring the dead within large earthen mounds, often called burial mounds or tumuli. This ancient tradition was common among various cultures, including the Native American tribes and the Celtic peoples. These mounds served as both graves and memorials, sometimes containing valuable grave goods, indicating the status of the deceased. The construction of mounds varied in size and shape, depending on the cultural context and the resources available. Some mounds were simple, while others were elaborate structures that could be several feet high. Archaeologists study these sites to gain insights into the burial practices, social structures, and beliefs of the cultures that created them.
