This lader is very fragile. Do not try to climb this one!

On a rooftops of the city hall of Montrouge with a lader, very usefull to climb from roof to roof.

The Montalets lader (the name of the place) is the highest level of the quarry. It's a long corridor, used to do some ventilation in the quarry.

The highest halls of the lantern tower of the Cathedral of Coutances. Its floor has been weakened over the years, it is no more open to the public.

At the top of the paper mill.
