It may be the best-documented slave burial ground in the District of Columbia.
European immigrants who built the C&O Canal and the City of Washington are also buried at Holy Rood, along with Civil War veterans and others. At the western edge of the cemetery is the grave of Joseph Nevitt, a veteran of the American Revolutionary War.Originally called Trinity Church Upper Grave Yard, the burial ground was established by Holy Trinity Catholic Church in 1832. It was enlarged between 1850 and 1870, and renamed Holy Rood Cemetery.
