    Harman Blennerhassett, a wealthy Irish aristocrat, settled on the wilderness island in 1798, where he built a magnificent mansion. Designed in the Palladian style (like Mount Vernon), the house contained 7,000 square feet of floor space. Its rooms were furnished with furniture purchased in London and Baltimore, oriental carpets, oil paintings, and porcelain made in Paris. The hardware on some of the interior doors was made of silver. Alabaster lamps were suspended from the ceilings by silver chains. A 2-1/3 acre flower garden and two huge lawns surrounded the house. It was one of the most elegant estates in Virginia and was the most beautiful home west of the Alleghenies. In 1806, however, Harman became entangled in a mysterious military enterprise with Aaron Burr. As a result, President Thomas Jefferson accused both men of plotting treason in attempting to establish an empire in the Southwest. Blennerhassett fled the island, but was captured and put into the Virginia State Penitentiary. Although Burr was tried and acquitted and Blennerhassett released from prison, the lives of both men were ruined. Interestingly, most historians now agree that Burr had set his sights on northern Mexico for his dominion, today's state of Texas. The exquisite mansion accidentally burned to the ground in 1811, eventually leaving no trace of its graceful, semicircular lines. However, modern archaeologists rediscovered its foundations in 1973. Through a continuing program of careful historical and architectural research, the mansion has been recreated for visitors to see. Work on furnishing its interior is still in progress. The Putnam Houser House This house was built in Belpre, OH in 1802. It was moved to Blennerhassett Island December, 1986. Thanks to the generous help of the Blennerhassett Historical Foundation and the donations of many local benefactors the house is being restored.
