• Work on the air-raid shelter under Plaza de Santiago began after the bombing of 1 April 1937, which killed 159 civilians.
  • With room for more than 1,000 people, the shelter was built under the square, making use of the crypts of the Church of Santiago.
  • Jaén had more than 30 shelters, some of which survive, such as the one at the San Juan de Dios Hospital or the one in this article.
  • When this article was made there was an art exhibition by the Ákaro collective, whose works can be seen in some of the photographs.
