St. Peter's Church, also referred to as St. Peter's on Capitol Hill, is a Roman Catholic church located on Capitol Hill in Washington, D.C., within the Archdiocese of Washington. Founded in 1820, St. Peter's is the second oldest Catholic parish in the City of Washington (but not the District of Columbia). The church building was originally constructed in 1889. However, it was destroyed by a fire in 1940 and rebuilt. The church's motto is, "To be a tangible manifestation of Christ in the community."
