One of Salem‘s most interesting buildings is the Pickering House at 18 Broad Street, which is the oldest house in the United States continuously occupied by one family. The earliest section, on the east, was erected by carpenter John Pickering, Sr., around 1651. The house was later expanded to the west in 1671 by his son, John Pickering II, and in 1751, Deacon Timothy Pickering raised the rear lean-to to a full two stories. A two-story ell was added in 1904. The front, with the new addition of two cross gables, was adapted to the Gothic Revival style in 1841. The fence also dates to this period. The house‘s most prominent resident was Timothy Pickering, the arch-Federalist politician (serving as a cabinet member, Senator and US Representative), who had been an aide to Washington during the Revolutionary War. Boston architect Gordon Robb, who also restored the Witch House in Salem, restored the interior of the Pickering House in 1948 and it was opened to the public in 1951 by the nonprofit Pickering Foundation.
