The Old Stone House was built in 1765 and is the oldest unchanged building in Washington, D.C. The house is also Washington's last Pre-Revolutionary Colonial building on its original foundation. Unlike many Colonial homes in the area, sentimental local folklore preserved the Old Stone House from being demolished.
The Old Stone House was constructed in three phases during the 18th century and is an example of vernacular architecture. During its history, the house was started as a one-story building and gradually became a used car dealership later. After a renovation in the 1950s, the Old Stone House was turned into a house museum.
The Old Stone House stands among the neighborhood's stores and restaurants as an example of local history for tourists, shoppers, and students. Today, the home is 85% original to its 18th-century construction.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
