Barcelona has the remains of several anti-aircraft bunkers left over from the Civil War, among them the one on Sant Pere Màrtir.

On a summit in the Collserola hills, where there was once a small sanctuary dedicated to Sant Pere Màrtir, later a small fort and then a signal telegraph (which has since been modernised into a communications mast), you can see the remains of some anti-aircraft gun platforms. This bunker, built in the early 20th century along with the Carmel bunker and others that no longer exist, such as the ones on Montjuïc or at Camp de la Bota (the Forum area), formed Barcelona’s anti-aircraft defences during the Spanish Civil War.

But the hermitage that gave the place its name hasn’t been forgotten, and it has its own small tribute. As you head up towards the mast at the top of the summit where the bunker stands, on the side opposite the bunker you’ll find what remains of the Sant Pere Màrtir hermitage, which is never without flowers and where a plaque explains its origins: ‘At the end of the 17th century, the Dominican fathers of the convent of Santa Catarina built a small sanctuary on this summit dedicated to Sant Pere Màrtir. Its privileged position, commanding the whole area, turned the hermitage into a fort and an exceptional historical witness to battles and military operations over the centuries’.

Here’s a link with more information about the Sant Pere Màrtir hermitage.
