St. John's has been long known as the "Church of the Presidents", visited frequently by neighboring chief executives and is the traditional site for an early morning prayer service and mass during inauguration days on March 4 and later January 20. Another historic episcopal church formed in the capital city, and which hosted nearby Maryland diocesan conventions, is the Church of the Epiphany (Washington, D.C.).

Construction of the Gothic Revival "Cathedral Church of Saint Peter and Saint Paul in the City and the Diocese of Washington" (usually known as the Washington National Cathedral) on Mount Saint Albans at the intersection of Massachusetts and Wisconsin Avenues in northwest Washington began with a charter issued by the United States Congress in 1893 and on September 29, 1907, the cornerstone was laid in the presence of 26th President Theodore Roosevelt and a crowd of 20,000 and continued with fits and starts until its general completion in the early 1990s, with a ceremony attended by 41st President, George H. W. Bush, serving as a "national house of prayer for all people" and becoming a national landmark for the Protestant Episcopal Church in the U.S.A. and icon for the Anglican Communion in the world.
