It's a great place. It is a 16th century cathedral, a mixture of day architecture, baroque, and gothic. It is a relic of the patron saint of Paris Saint Genevieve. As the church from the inside is typical of most Paris cathedrals, it is distinguished by its amazing designs, and the elaborate architecture that is unparalleled. This church is distinguished from other churches in that the Pantheon is close to it, where you can take a wonderful tour that includes the two places. It is an excellent experience and well worth the experience.
