A remarkable reminder of the early Federal era, Judge Thomas Smith's house was built in 1770–1771 and purchased by David Espy, an attorney and Revolutionary activist. The three-bay stone house, with an interior end chimney, has two rooms on each of three floors with a stair hall on the west side. The building has had a storefront since George Washington used it as his headquarters in 1794, when he commanded 7,000 federal troops to quell the Whiskey Rebellion, the only sitting president to directly command his army in the field.
