The new law of coasts passed by the conservative Spanish government and allowing construction only 20 meters from the coast (it used to be 100m), a scandal on its own right, will have direct effects on the already extremely fragile protection of the cave of Praileaitz, located within an active quarry and holding evidence of human existence from the Magdalenian period but also, we know now, from Neanderthal times some 100-120 Ka ago.
Years ago, the (then unelected) Western Basque Government limited the protection area to just 65m, considered by all experts wildly insufficient (Jean Clottes asked for 500m, for example), however a tribunal ruled later that 50m was enough. This new law allows for constructions and economic activities (such as the quarry) to take place just 20m away from the cave galleries, what may be very damaging.
There are possible mechanisms to counter this legislation but require of a political will that so far has been lacking or rather negative, hostile.
The utmost fragility of the cave is very apparent in this air view highlighting the archaeological sites near the controversial quarry:
