This is the biggest and most splendid church I have ever seen. It was unexpected that such a small country as the Vatican should be able to build such a quality church. Today is Thursday, not a holiday, but there are so many people visiting St. Peter's Cathedral in the Vatican. I wanted to visit the Vatican Museum. Because of the serious deviation of the bus address found on the Internet, I walked a lot of time. When I finally saw St. Peter's Cathedral in the Vatican, I thought it was the Vatican Museum. I stood in line for about 40 minutes, but I found it was the church. It was in Vatican (Italian). I didn't know the Chinese name. I asked my Taiwanese compatriots about it. Just tell me. If you only visit the inside of the church, free of charge, it's unexpected. If you want to visit the dome part of the church, climb the stairs for 6 euros and lift for 8 euros. If you are young and energetic, you should climb the stairs, because the stairs are not easy to build and when you reach the highest point, you can have a 360-degree view of the whole city of Rome, including Vatican City. Amazing!
