Spanish castles: more than half at risk and no inventory to save them

Published on May 09, 2026 | Translated from Spanish

Spain's castle heritage is crumbling. More than half of the historical fortifications are at risk of collapse due to lack of investment and neglect. Experts warn: there is no updated official inventory reflecting their real state, which prevents prioritizing interventions. Meanwhile, rave parties in protected sites and partial collapses are evidence of a lack of protection that urgently needs to be addressed with data and concrete plans.

DESCRIPTION: Ruins of a medieval Spanish castle with cracks and overgrown vegetation, in the background lights of an illegal party and a fallen 'no entry' sign.

Specialists are calling for a centralized system that catalogs each fortress with homogeneous technical criteria: level of deterioration, structural urgency, and historical value. Tools such as 3D scanners, inspection drones, and monitoring sensors would allow for accurate reports without the need for invasive interventions. With this information, administrations could allocate resources efficiently and halt the progressive deterioration that today turns castles into rubble.

While experts call for an inventory, some entrepreneurs already have their own restoration plan: renting out the ruins for clandestine parties. If the castle is falling down, at least let techno music play. Of course, without an official inventory, no one will know if the site can withstand the bass boost. The Spanish solution to heritage: if you don't take care of it, at least let it serve for the after-party.
