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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
