El Molino 1936

Unfortunately a scan of a scan so it's not very good quality.
You can see the the Molino theatre at top right. At the beginning of the Spanish Civil War barricades were set up on the main boulevard Paral.lel in front of the theatre to prevent pro-Franco troops reaching the port.
The theatre itself was requisitioned by an anarchist group until late 1938.
