Shaft XIII and its history: Dug during construction of the Blaisy-Bas railway tunnel in the 1850s.
It is one of 22 extraction shafts spaced 200m apart, which allowed the cuttings to be evacuated from above during the works.
It is now used as a ventilation shaft and allows the excess pressure due to the passage of trains in the tunnel to be evacuated.
