About Blennerhassett Island Historical State Park
A Palladian mansion once stood here, built by Harman Blennerhassett and his wife Margaret Agnew, whose household became tied to the alleged conspiracies surrounding Aaron Burr. The original house burned down in 1811, and a detailed replica was constructed on its foundations in the 1980s, following a Federal style with Palladian details. Visitors can tour this reconstructed mansion, set on the small Ohio River island the park occupies.
Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
