There is something really cool about the Pantheon. I feel like I just traveled to Rome on a budget! It's huge and so majestic. This building is full of light which for French buildings is a change. Some parts are being renovated but it almost was not noticeable.
Well, when I said light, I meant until you go visit the crypt that is. But the crypt is one of the biggest I have ever seen. You can find the tomb of all the best of the best minds and talents of France: Victor Hugo; Zola, Voltaire, Rousseau, Alexandre Dumas, Jean Moulin, Pierre and Marie Curie... just to name a few! I usually don't like paying to see things in Paris but I have to say it was money well spent.
