The Coat an Noz Castle was built in 1880. The original owners went bankrupt, they sold the building to another family who has never maintained the castle. Today, he is ruined in a worrying state.

A view of the curtains of the roof of an art deco building 37 street of the Louvre. This building was built in 1934 by the architect Fernand Leroy and Jacques Cury to accommodate both newspapers Paris-Midi and Paris-Soir. Five years later, two million newspapers are coming out of the printing press in the basement of the building. The construction, modern, is fully planned for the implementation of newspapers. There is even a big diesel engine provided electricity in case of power failure. The upper floors are the most beautiful terraces where guests are received in peace, enjoying the magnificent view.
But like any business in the world war two who worked with german army, management changes hands for the release and communists newspapers took in commands: Ce Soir, Liberation, National Front (far left a newspaper) and humankind. Later Dawn and the Figaro will merge in 1985. It is said that some nights where humanity and the Figaro had printed, we brushed the confusion of pages.
This ship (as some people called the building) has been completely renovated from 2007 to 2008 and was included in the supplementary inventory of historical monuments. Some renovations are debatable but you can not stop progress.

On the roof of the tallest building in the Renault factory on Ile Seguin. The latest model of car produced in this building was the Supercinq. Two huge cranes and many compressors are aligned on a hundred meters. Imagine that there is piping under there!

Overview of the site. The central building was designed by architects Raymond Lopez and Marcel Reby and was completed in 1959. It is a unique example of building completely dry mounted by the use of metal structures and features glass curtain walls are totally independent of the metal structure. It was added to the inventory of historical monuments, but the tribunal has overturned this ruling. For what? Selling appartments to freaks?

The quarry Montesson was used (as often) for the cultivation of mushrooms. Long abandoned, the quarry of building stone has been cut in half during the construction of the highway A14. In 2010, further work has finally destroyed this beautiful part of the quarry.
