Friendship Hill is a parcel of land Шаблон:Convert in size, located on the east bank of the Monongahela River between New Geneva and Point Marion in rural southwestern Pennsylvania. The property's main house, also known as the Albert Gallatin House, is located atop a bluff that is the high point of the property.
The house is made up of seven sections. The earliest of these is the original brick house built in 1789. This structure was constructed in the Federal style with a Flemish bond. Along the north side of the brick house, a simple frame dwelling was added in 1798. The Stone House was the next structure added by Gallatin in 1823; this is a Шаблон:Frac-story structure, the largest section of the total house. This was the only structure which Gallatin did not build and oversee himself. This portion was built and overseen by one of his sons, Albert Rolaz Gallatin. A stone kitchen was added in 1824, which was the last addition of the Gallatin era.
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. These portions were built by the later owners of the house.
