About Blennerhassett Island Historical State Park#

Blennerhassett Island Historical State Park is a state-run historic site on an island in the Ohio River near Parkersburg, West Virginia, preserving the estate associated with Harman Blennerhassett from the early 19th century. The island preserves a reconstructed mansion and interpreted grounds as a public historic attraction.

The main attraction is the reconstructed Blennerhassett Mansion, presented as a museum with period rooms and exhibits about the Blennerhassett family and island life. Visitors typically combine the mansion tour with guided walks of the island grounds and interpretive displays at the mainland visitor center.

Harman Blennerhassett established the estate in the early 1800s; the original house was destroyed in the 19th century and the current mansion is a later reconstruction built on the original foundations for historic interpretation. The island is also noted for its association with the early 19th-century political controversy involving Aaron Burr.
