To experience more details about the cap's function, see the next photo please.

If you imagine that until before a few years a pit bank has been here, that the miners started their work here, that the shaft tower of the important Mont-Cenis colliery stood here, that this colliery provided the miners with work and money - insn't this unbelievable ?
