Some European scenes were shot in Keszthely, Sóskút, Fertőd and Kecskemét, Hungary. British officers ransacked an abandoned Continental Army war room in a scene shot in the Robert Carter house. Williamsburg's Public Hospital was in the background of the tent encampment of the Continental army which Adams visited in the winter of 1776, which was replicated using special-effects snow. The College of William and Mary's Wren Building represented a Harvard interior. Scenes were also filmed at the Governor's Palace. Sets, stage space, backlot and production offices were housed in an old Mechanicsville AMF warehouse in Richmond, Virginia. Some street scenes with cobblestone pavements and colonial storefronts were shot in historic neighborhoods of Washington, D.C., Boston, and Philadelphia.
