The land now known as the District of Columbia was once part of Prince George's County, Maryland. A congregation which later became known as Rock Creek parish was founded in 1712, and by seven years later had built a chapel of ease for (Broad Creek Parish), which was the spiritual counterpart to secular government in Prince George's County. The congregation built a larger, Georgian style building in 1775, which is now known as St. Paul's Episcopal Church, Rock Creek Parish (Washington, D.C.). It is the oldest religious institution within the District of Columbia. The former glebe (farm to support the parish priest) became the non-denominational Rock Creek Cemetery, now also home to the InterFaith Conference of Metropolitan Washington.
