The Hill-Woodman-Ffrost House in Durham, New Hampshire, is purportedly one of the oldest buildings in the U.S state of New Hampshire. Located within the Durham Historic District, the owners claim that the "original homestead" was built in 1649. The building is now part of a hotel known as the Three Chimneys Inn & ffrost Sawyer Tavern.
In 1649, Valentine Hill built a home north of the Oyster River near his mill. The tavern's back ell is alleged by the owners to be Hill's original house, with later additions made by Nathaniel Hill around 1680. In 1694, the house survived a Native American attack, the Raid on Oyster River, which destroyed many of the buildings in the area. Jonathan Woodman eventually inherited the property from his Hill family members; he deeded it to George Frost at some point after 1796, and the Frost family owned it until the 1980s.
