 In the Louvre area, the meridian line marked by the Arago medallions actually runs through the museum and the great courtyard at a spot considerably to the east of the "Inverted Pyramid".The medallions in the museum are behind ticketed access points, while the "Inverted Pyramid" is located in a public mall next to the museum.Other landmarks said to lie on the line are Arques and Conques, the Lady of the Roses cathedral in Rodez, St. Vincent's in Carcassonne, and the Church of St. Stephen's in Bourges, and Rennes-les-Bains.
