St. John's Episcopal Church, Lafayette Square – 'Church of the Presidents'

St. John's Episcopal Church, located directly north of the White House on Lafayette Square, is commonly nicknamed the 'Church of the Presidents' because many U.S. presidents and first families have attended services there since the early 19th century. The church has been used for presidential worship, memorials, and official White House-related services. Its proximity to the White House has made it a traditional site for presidential participation in religious observances.
