Washington, D.C. is loaded with tourist sights. From the White House to the Lincoln Memorial, the city is rich in architecture and history. What the U.S. capitol also has is many churches. St. John’s Episcopal Church, across the street from the White House, dates back to 1816. Georgetown Presbyterian Church, a congregation that formed in 1780, has been housed in its current building since 1871. Washington National Cathedral, host to many important memorial services and celebrations, was officially completed in 1990 following 83 years of construction.
