Old Stone House

The Old Stone House, located at 3051 M Street in Georgetown, was built in 1765, making it the oldest standing building in Washington, DC. The exterior of the house is constructed of locally quarried blue granite. The house was built by Christopher Layman, a cabinetmaker by trade, as both a residence and a shop. Layman died shortly after constructing the house. It was sold to Cassandra Chew who added a wing to the rear of the house in 1767. The street (then called Bridge Street) was a main thoroughfare for road traffic from the Western frontier and paralleled the canal into Georgetown. Read more…
