Mushroom area in a big quarry. Bags are still goods.

The mushroom bags of the great quarry of Vic sur Aisne.

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!

The beginning of the first mushroom area. The bags are also damaged the door.
