Dangerous Blind Spot: Why a Crane in Palma Fell into a Hidden Cistern

Answer

Why are hidden cisterns a risk during construction work in Mallorca?

Older parts of Mallorca often contain forgotten rainwater tanks, wells, or other underground cavities that are not always visible from the surface. If heavy machinery is brought in without checking the ground conditions first, the surface can collapse unexpectedly. That is why subsurface checks are important before work with cranes or similar equipment.
