National Shrine of the Immaculate Conception - Washington, D.C.
The Basilica of the National Shrine of the Immaculate Conception remains the largest Roman Catholic church in North America, one of the 10 largest churches in the world. Its design was based on Old World cathedrals, a Romanesque-Byzantine creation made of stone, brick, tile, and mortar (no steel).
St. Paul’s Chapel - New York
The chapel building of Trinity Church, an Episcopal parish in lower Manhattan, is a 1766 building long noted for its Late Georgian church architecture. It will remain forever linked to the 9/11 terror attacks of 2001, though. Situated across the street from the World Trade Center, the chapel itself suffered no physical damage despite its proximity to the horrific events unfolding steps away.
