Explore an old Civil War air-raid shelter in Onda that tells the story of the town.

Underground air-raid shelters were widely used during the Civil War, protecting the population from bombardments and any other kind of attacks. Some of these shelters have survived to the present day and have been transformed into places of remembrance, museums and places to visit where you can explore the recent history of Spain and keep it alive.

A case in point is L'Algepsar Cave in Onda. The cave showcases the historical events that shook this part of the province of Castellón from 1936 to 1939. An exhibition, complete with information panels, has been set up in the tunnel which forms the entrance to the cave. This area has been renovated to tell local history and raise awareness among visitors.

Sitting at the feet of Onda Castle, L'Algepsar Cave is an essential part of the area's heritage. It was used as a shelter during the bombardments that the town suffered in the June of 1938, when it was on the front line of fire. Now, we are fortunate to be able to visit the cave and learn from it.

Since its inauguration as a place of remembrance, L'Algepsar Cave has been well received by the public. It is free to visit, but you do need to book in advance. Come and take a look around, and make the most of the opportunity to explore each and every nook and cranny of the cave.
