When I was drowsy in the car and my guide woke up with a shout from the bus, I looked blankly at the building and square in front of me. It was a very modern and special building. When I wondered what the attractions were, the tour guide had already led the team in front of me and walked in all the way. It turned out to be a church! Such a building is a church! St. Mary's Cathedral! This external and internal structure completely overthrows the traditional church! Looking up at the top of the building, the center presents a huge cross of sunlight and glass, but there is no pillar inside the church. There are tens of millions of churches, and very few churches can be remembered at a glance. This is the most amazing and personalized church besides the Saint Family Church in Barcelona. Later, I learned that this church was created by Pei Yiming, the famous Chinese designer who designed the Suzhou Museum and the railway station. No wonder it was so creative.
