The restored farmhouse and formal garden was the scene of trade with the Indians and settlers along Beaver Dam Creek and later part of the Gettysburg Campaign. On July 2, 1863 Union and Confederate cavalry collided head on here. Washington had his horse shod at the farm's blacksmith shop on his return from quelling the Whiskey Rebellion. The outbuildings at Tate Farm are original: a summer kitchen with walk in fireplace, a granary, spring house, carriage house, garden shed, outhouse, stable, and large barn with a cannonball hole.
