One of the largest cathedrals in the world, the National Cathedral is more than an Episcopal cathedral; it is a national shrine. Being the site of several significant memorial services, the cathedral lives up to its role of a ‘spiritual home for the nation’. The final Sunday sermon delivered by the Rev. Dr. Martin Luther King, Jr., is only one among the many notable historic moments that the cathedral has witnessed. The flying buttresses, gargoyles, crypts, an enormous vaulted ceiling and intimate chapels all contribute to this architectural marvel. Furthermore, the curving walkways, well-kept hedges and spacious lawns invite exploration. When in Washington, a visit to this national treasure simply cannot be missed.
