The well

The well located in the center of the « castle » part of the site was entirely dug into the limestone rock, which represents a feat when we consider its interior diameter (2.50m) and its depth (54.50m).

Contrary to what was previously believed, it does not reach the level of the Meuse but quite simply a water table located in the rocky massif. With the cisterns and other wells it allowed the water supply to the occupants of the fortress, a particularly important fact in the absence of any source in Poilvache. This dependence on water seems to have been fatal in 1430, when the garrison attacked by the army of the Prince-Bishop of Liège could no longer use the well whose water had become unfit for consumption.

Among the legendary facts linked to Poilvache we will cite the presence of a « gatte d’or » which would have made the well its shelter.
