The first time I saw the Arc de Triomphe, it was inadvertently. Everyone knows the gladiators and the Colosseum in Rome. They have seen the Colosseum, walked among the ruins of the ancient Roman Square and looked at the ruins. Suddenly, they found this well-preserved and exquisitely carved building. I think the first thing most people see must be the Arc de Triomphe in Paris. Perhaps the latter is inherited or inspired from this vein. Completely stony buildings allow them to survive for thousands of years without being destroyed. It's not easy to see them now. Just as a tourist, I can not understand the words and patterns carved on it, but simply feel that the carving is exquisite and delicate.
