Fort San Cristóbal

Pamplona, Spain

The Fort Alfonso XII or San Cristóbal is a fort located on the top of the mount San Cristóbal, 4 km from Pamplona, Spain. It was built after the Carlist War of 1872-1876 because Carlists succeeded to reach Pamplona (controlled by the liberal Government) with their artillery from this and other mountains surrounding Pamplona from the north. 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. Another example of this is the fort San Marcos, near San Sebastián.

The fortress was built from 1878 to 1919. The top of the mountain was blasted and most of the construction is underground, so it is barely visible from the outside. Its three floors have an extension of 180,000 m². It is surrounded by a moat and the total extension of the facility is 615,000 m².

After the revolution of 1934, nearly 750 revolutionary convicts were imprisoned there. Most of them were amnestied after the electoral win of the left in February 1936. 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 inmate population in the fort rose to more than 2,000.

On May 22, 1938, some prisoners organised a massive prison break. 792 prisoners fled, but unfortunately for the escapees one of the guards sneaked his way to Pamplona, and gave notice. 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. Fourteen of the arrested who were considered the leaders were sentenced to death. Most fugitives were intercepted during the following days.

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. In 1988, a sculpture was erected to honour the memory of the Republicans who died there. The fort ceased to be a prison in 1945.

The Ministry of Defence still owns the facility although the last troops left it in 1991. 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.

Great historical place to visit. It is open for tours of you call to special department. You can sneak in though. If you keep on going along the right side, in about a 400 meters there are stairs down to the fort. Then you can explore the fort prison complex. There is not much of anything left. I only explored areas near by though. You can go up to the second floor cells, the go to the first floor cells. Bring flashlight.

Nice views of Pamplona and surroundings, if you're dressed for the mountain you can even have a walk around the fortification, it's quite impressive and entertaining, you cab even get inside where it's dark and somewhat scary but yet safe, also nice views from the other side up in the hill of the rural area outside Pamplona.

Unexpectedly tremendous visit to a military owned permanently closed facility near Pamplona, built in late XIX century to defend the city from a nothern attack, and used as a prison during Republic and civil war, the place remains still (even if ruined and abandoned) as an historical place.

Hohenwerfen Castle

Hohenwerfen Castle stands high above the Austrian town of Werfen in the Salzach valley. The castle is surrounded by the Berchtesgaden Alps and the adjacent Tennengebirge mountain range. The fortification is a 'sister' of Hohensalzburg Castle both dated from the 11th century.

The former fortification was built between 1075 and 1078 during the Imperial Investiture Controversy by the order of Archbishop Gebhard of Salzburg as a strategic bulwark. Gebhard, an ally of Pope Gregory VII and the anti-king Rudolf of Rheinfelden, had three major castles extended to secure the Salzburg archbishopric against the forces of King Henry IV: Hohenwerfen, Hohensalzburg and Petersberg Castle at Friesach in Carinthia.
