Capitol Hill Parks includes those park areas managed by National Capital Parks-East between 2nd Streets NE and SE and the Anacostia River. Included in this group are Lincoln; Folger, Stanton; and Marion Parks; Maryland Avenue Triangles; Pennsylvania Avenue Medians; Squares and Triangles, including Seward Square, and Potomac Avenue Metro Stations, Twining Square; and otherinner-city triangles and squares.

When Pierre L'Enfant submitted his design for the Capital City of Washington in 1790, a system of grand avenues, public buildings and grounds dominated the overall plan. Many of the parks, medians, circles, squares and triangles of Capitol Hill Parks evolved from this plan and its subsequent modification, in 1901, by the McMillan Commission. Their purpose is to provide urban greenspace within the City of Washington for relaxation, aesthetic enjoyment, and historic commemoration.
