Located on the high ground northwest of Washington. The traffic is not very convenient. The nearest subway station is cleveland park metro staion , or woodly park-zoo metro station , two kilometers away. It takes 20-25 minutes to walk. We rented public bicycles to ride there. This church is very grand, sculptures, flower windows, etc. are worth watching carefully. We were just here to appreciate the beauty of religious architecture, but we happened to meet Sunday religious events. Thousands of people were doing religious rituals. We quietly found seats and sat down, and there were books such as Bibles in the desk drawer. The ritual consisted of many parts, and I didn't understand the meaning. However, when the organ played a grand sound echoed throughout the church, and when the choir sang a celestial harmony, the melody instantly inspired the heart. How magical, music can connect me with religions that seem impossible to meet, and resonate. To experience Christian culture in this way certainly adds more meaning to our trip. The National Cathedral has a souvenir shop selling cross-shaped accessories, rose window pattern T-shirts and other products, some cute, this commercialization, closer to religion and ordinary people. In addition, there is a door behind the church, inside is actually a quiet and beautiful garden.
