The Old Stone House is the oldest unchanged building in Washington, D.C., United States. The house is also Washington's last Pre-Revolutionary colonial building on its original foundation. Built in 1765, Old Stone House is located at 3051 M Street, Northwest in the Georgetown neighborhood. Sentimental local folklore preserved the Old Stone House from being demolished, unlike many colonial homes in the area that were replaced by redevelopment.
The Old Stone House was constructed in three phases during the 18th century and is an example of vernacular architecture. The house was built as a one-story structure. Additions were later made, and it was used both as a residence and for business.
