If DC city designer Pierre L'Enfant were still alive today, he would be happy with Sheridan Circle, regarded as one of DC's last great circles/squares. He initially envisioned such open places the focal points of residential neighborhoods and they were intended to provide a sense of rhythm and organization to the layout of the city. After the Civil War, many of these squares and circles were chosen as locations for monuments and memorials to war heroes, and they were transformed from informal playgrounds to these more formal monuments.
The bronze statue of Civil War General Philip Sheridan, depicting his role of leading his cavalry to victory at the Battle of Cedar Creek in Virginia's Shenandoah Valley in 1864, was completed in 1908 by Gutzon Borglum, the sculptor of Mount Rushmore. A nice place to stop and hang if you are on your way to an embassy event or are embassy hopping as grandiose former mansions (now embassies and ambassadors' residences such as Greece, Ireland, Romania, Turkey, Latvia, and the Philippines) surround the statue.
