Moundville Native American Festival. October 4 - October 7, 2000. Poster. The Moundville site, occupied from around A.D. 1000 until A.D. 1450, is a large settlement of Mississippian culture on the Black Warrior River in central Alabama. At the time of Moundville's heaviest residential population, the community took the form of a three hundred-acre village built on a bluff overlooking the river. Within the enclosure, surrounding a central plaza, were twenty-six earthen mounds, the larger ones apparently supporting noble's residences alternating with small ones that supported buildings used for mortuary and other purposes. 23"w x 17"h.
