The Ditch recounts the story of a forgotten defence line built on Öland, a small island on the east coast of Sweden, during the Second World War. The line was intended to act as an obstacle for tanks, splitting the island into two parts near the village of Föra. In the book, Cederqvist’s images are combined with documentary material from the Swedish War Archive, records which remained classified until the 1980’s. 

Work on the defence line was based on a number of strange assumptions and it was not long before things started to go wrong: the ground swallowed more water than planned, the pump was undersized and costs skyrocketed. Eventually, the leader of the project, Raoul Thörnberg, was court-martialed. The so-called ‘Föralinjen’ came to represent a notable failure for the Swedish military, and something they would prefer to forget. Traces of the project – reminiscent of an abandoned piece of land art – remain visible in the landscape.
