France, Paris, Arena of Lutetia

The Roman Arena that was discovered by Théodore Vaquer during the building of Rue Monge, in the 5th arrondissement, between 1860–1869. It was first built in the 1st century AD. Victor Hugo created a preservation committee called "la Société des Amis des Arènes" to preserve it. However in the photo, taken by me in May 2014, can be seen the line of apartments on Rue Monge that cover the remaining third of the Arena.
