Friendship Hill was the home of early American politician and statesman Albert Gallatin (1761–1849).
The house overlooks the Monongahela River near Point Marion, Pennsylvania, about 50 miles (80 km) south of Pittsburgh.
Friendship Hill is a parcel of land 675 acres (273 ha) in size, located on the east bank of the Monongahela River between New Geneva and Point Marion in rural southwestern Pennsylvania.
The rest of the additions include a State Dining Room in 1895, a south bedroom wing completed in 1902, and the servants' quarters added in 1903.
He became involved in real estate speculation in western Pennsylvania and Virginia not long afterward, and purchased the land and house that became Friendship Hill in 1788.
