The Old Stone House in Georgetown, Washington, DC, is the oldest building in Washington that has not been altered in any way. This rustic house was constructed in the mid 18th century as a simple, one room building facing M Street. The couple who built the land and constructed the home, Christopher and Rachel Layman, moved in with just simple hand tools, a stove, some bibles and a few small pieces of furniture. Christopher died relatively young and Rachel subsequently sold the house to widow Cassandra Chew, who renovated the house, adding a second and third floor. After Chew, The Old Stone House was passed down and sold to other individuals and had been used for everything from a used car dealership to a small store.
The Old Stone House is now a part of the National Park System and open for public tours. The house has been restored to what it looked like in the late 18th century, although it continues to have the additional floors that were not present at that time. The Old House contains a gift shop and an outdoor garden area that is a popular destination for wedding photos. Local residents also use the garden for sitting outdoors when weather permits, to have a feeling of being in the midst of early American history.
