Fort San Cristóbal (Spain)

The advances in artillery during late 19th century forced the military authorities to build this kind of fortifications in order to control mountains and hills close to important towns.

During the early stages of the Civil War (July-September 1936), the military rebels strong in Navarre unleashed a terror campaign against inconvenient, dissenting civilians in the rearguard.

The Nationalist military rebels strong in Navarre went on to organise a manhunt, with only three managing to get to the French border; 585 were arrested, 211 were shot dead.

"[1] Those living through the military operation were brought back to the fort, imprisoned, and left to die of famine and disease, totalling more than 400.

Although there has been several projects for recovering the fort and giving it a new use and in 2001 it was decreed "good of cultural interest", it remains today abandoned and ruinous.
