Old Stone House garden overlooking the C&O Canal

The Old Stone House in Georgetown, built circa 1765, is the oldest unchanged building in Washington, D.C., and is managed as a historic house museum. Its rear garden adjoins the Chesapeake & Ohio Canal towpath and provides a tucked-away, low-elevation view of the canal and the adjacent Georgetown block. The site is open to the public during posted hours and is noted for preserving an 18th-century urban streetscape within Georgetown.
