The cathedral is at 6 Parvis Notre-Dame - Pl, Jean-Paul II, 75004 Paris, France. It is the tallest building for one hundredth in the city. A great spot in Paris
Overrun with dead bodies and a public health hazard, the Catacombs were cleared out in 1862 and moved to another site. I think this is one of the top spots in Paris.
Montmartre was built in the Romano-Byzantine style during the 19th century as a place of worship dedicated to Christ's heart. It is considered to be the best place in Paris.
