The structure of the dome of the Hôtel-Dieu de Lyon was made of wood. But during the Second World War, a fire destroyed it Sept. 4, 1944. It was only that funds be provided by the state for its reconstruction, hospices have not enough money. The repair was carried out by the Chief Architect of Historic Monuments Jean-Gabriel Mortamet according to architectural plans of Soufflot.

A beautiful writing in the second underground level of the quarry of Port Mahon.

The limestone quarry of Chanaz is a smaller operating on three levels. The ceiling height is between 5 and 10m. Sometimes, holes in the floor let you see underground levels.

The network size is almost 4km developed. It was exploited from 1860 to the end of the Second World War to make cement. Portions was reused as mushroom farm thereafter (row crops and cultures in bags).

In this photo taken at the highest level, we see the intermediate level, row crop bottom right and even two holes overlooking the lower level. This is the most impressive part of the network with large volumes!

Built in 1522, the castle of the bull is a defensive fortification. It was upgraded by Vauban in 1700. The work took about 45 years. The castle of the bull has never been a major military role. It has been used as a prison for a long time. In 1914 he was classified a historical monument. This does not prevent the Germans using it as DCA during the Second World War. After the war, the sailing school Morlaix settles for 20 years. Then in 1980, it is abandoned. Fishermen love to come and make a fire to eat but they ransacked the wood fittings. Today it is finally restored and visited by the public.

The underground limestone quarry of Bazemont, located in the Yvelines, was exploited for its rough limestone. There are still several excavations along the quarry road. People said in the village that the steeple of the cathedral of Chartres was built with stone from this quarry.

The quarry is also witnessed the wars of the 19th century. There are many drawings of ancient time. Drawings of soldiers, praise God, graffiti. Second quarries are reused in mushroom places. You can see the remains of the culture of the mushroom into stacks.

People of Bazemont also operated quarries in manufacturing lime from limestone. A furnace that access was by way of Grignens are still at the bottom of the valley Rogère.
