About This Park

Located on a small island in the Ohio River, Blennerhassett Island Historical State Park features a Palladian mansion on the island and a museum of regional history located in Parkersburg. This unique state park is visited by 40,000 people each year. This historical park is accessed by a sternwheeler riverboat from Point Park on 2nd Street in Parkersburg. Once on the island, visitors may enjoy tours of the grounds and mansion and horse-drawn carriage rides. Tours are offered when the park is open, from May through the last weekend of October. "Mansion by Candlelight" is a premiere event for two nights only in October. Other special events are offered throughout the year.
