Since childhood, I have heard the infatuation of Cassimodo, the eccentric bell tower, and a familiar feeling of Notre Dame in Paris. The outside of the church was solemn and solemn, with huge doors surrounded by statues, one layer after another. Into the interior, countless vertical lines attract people's attention. Dozens of meters high vaults are dimly visible in the dim light, twinkling, and religious reverie. It seems that above is heaven, where we can talk to God.
