Why locals love it
Less known than any other panoramic spots in Paris the Pantheon is quite an experience, beside visiting an impressive classic architecture you should plan your visit on a sunny and clear day in order to get up to the dome. The stunning column peristyle is already worthy the visit but the sight of Paris all around is definitely worthy to be seen.
Why you should visit it
Feel the "French Glory" at its best.
Go there on a sunny day, during the week in order to avoid weekend's big crowd.
