In the past, not very long ago, Le Balze were used by man as a shelter.
The several doors we can still see today at the foot of the earth walls
are an evidence. The local inhabitants dug several caves inside Le
Balze, to use them as a shelter in case of rain or as a deposit for the
agricultural tools and the farmyard animals.
The entrance was made
safer by supports and beams avoiding eventual landslides, but it had no
support within, where you could only trust in the compact texture of
the muddy sand.
Also during World War II the caves dug in Le Balze were used by the local population to conceal from the German army.
