Washington National Cathedral

A frequent site of nationally significant memorial services, the National Cathedral is open to worshipers of all denominations. Under construction for most of the 20th Century and completed and consecrated in 1990, this Gothic cathedral is Washington D.C.'s fourth-tallest structure. Flying buttresses, gargoyles, crypts, a 98-foot (30-meter) vaulted ceiling and intimate chapels contribute to this architectural masterpiece. The grounds invite exploration with curving walkways, well-kept hedges and spacious lawns.
