Fort San Cristóbal (Spain)
Historique
The Fort Alfonso XII or San Cristóbal is a fort located on the top of the mount San Cristóbal or Ezcaba (892,8 m above sea level), 4 km from Pamplona, Spain. It was erected following the 1872-1876 Carlist War to control an strategic point towering over Pamplona. It was later made into a makeshift prison during the 2nd Spanish Republic, bearing witness during Civil War to a halfhearted massive prison break by leftist prisoners that ended up with the death of hundreds.
