Fort Hill State Memorial is a nature preserve containing one of the best preserved Indian hilltop enclosures in North America. The Hopewell Indians (100 B.C.-A.D. 500) constructed the 1 1/2 mile long earthwork hilltop enclosure as well as at least two ceremonial buildings and probably a village in the Brush creek Valley.

Lying at the western edge of the Allegheny Plateau, immediately south of the glacial boundary, this hilly area contains an impressive diversity of bedrock, soils, flora, and fauna. There are 11 miles of hiking trails at the 1,200 acre preserve as well as a picnic area. The museum reopened in the fall of 2000 after an extensive renovation. New exhibits include a variety of hands-on and interactive, multimedia displays depicting the geology, flora and fauna of Fort Hill..
