Refugi antiaeri en el pas soterrat d'entre el C/St. Antoni № 93 i Muralla del Castell № 50

The Refugi Antiaeri located in the underground passage between Carrer Sant Antoni № 93 and Muralla del Castell № 50 in Calella, Spain, is a Civil War-era air raid shelter. Built during the Spanish Civil War (1936-1939), this shelter was part of the extensive network of civilian protection structures constructed to safeguard the population from aerial bombardment. The shelter's location in the historic center of Calella, near the medieval castle walls, reflects the strategic importance of protecting urban areas during the conflict.
