I think Picasso would approve of this version of his great work.

Someone has painted his Guernica on a bunker constructed during the Spanish Civil War by the republicans to protect part of the Catalan coast had Franco launched a sea attack.

And after the war was concluded an impoverished family of seven even lived in it, as there was nowhere else. And presumably free.

Walk up the coast from St Vicencs de Calders – about 30 miles south of Barcelona – through Sant Salvador and before you reach Calafell, you pass Bunquer d’ametralladores de les Madrigueres. That’s the Catalan name for it.

The text on the board tells the story of the family who decided to live there in 1949. One of the children Trinidad Casas Perin lived there with two sisters and two brothers. I don’t remember any furniture, she says. It was cleaned up and all the cooking was done there.

They lived there until 1953 when the family was able to rent a place and moved to a new home, which by comparison said Trinidad: “To me seemed like a palace.”
