Búnker 1 de Camposoto, Military bunker at Camposoto Beach, San Fernando, Spain.
Búnker 1 of Camposoto is a concrete fortification located at the northern end of Camposoto Beach in San Fernando, overlooking Cadiz Bay. The structure contains multiple firing positions and internal chambers designed for monitoring and defending the coastline.
The structure was built between 1936 and 1939 during the Spanish Civil War as part of the coastal defense systems protecting Cadiz Bay. After the conflict ended, it remained in place, a surviving remnant of a period of intense military activity in the region.
The structure stands as a visible reminder of how Spain's coast was fortified during a turbulent period, showing the everyday reality of wartime defense. Walking around it helps visitors understand the concerns and engineering solutions of that era.
Visitors reach the structure via the coastal path from San Fernando, which runs along the beach and is well marked. Informational panels on site explain how it functioned and why it was built in this location.
The structure preserves its original construction from the 1930s, including thick concrete walls and firing ports oriented toward observing naval movements in the bay. These features make it a rare example of how military technology was applied to this coast.
