Looking east through section Circle-South at Prospect Hill Cemetery in Washington, D.C., in the United States in 2014. Prospect Hill Cemetery was added to the Register of Historic Places of the District of Columbia (a listing of historic sites maintained by the city) in 2005. The central path divides section Circle-Right South (left) from section Circle-Left South (right), while the curving path defines Chapel Circle. Within Chapel Circle, a chapel once stood. The chapel was built in 1900 and existed until at least 1950, but was demolished at some point. A small circular garden and plaque now mark the site.
