I borrowed Hugo's masterpiece in school. There are a lot of words about architecture in it. I'm ashamed I haven't finished reading it. But when I was very young, I saw movies on black-and-white television, and Cassimodo blurted out. It's a pity that I didn't get to the Bell Tower because I was late. It takes a long queue to get into the hall without buying tickets, and the queue goes very fast. For the first time I saw the priest lead the man into the confession room. I think the local devout believers must not like so many tourists. As a functioning religious place, balancing the relationship with tourism is a test. Next time you must come earlier and buy tickets to the Bell Tower.
