Bunker 599, Military bunker at Diefdijk, Culemborg, Netherlands.
Bunker 599 is a concrete structure along the Diefdijk with reinforced walls that rises about 4 meters high. The building was part of a chain of defensive installations that formed a connected line of protection.
This structure was built in 1935 as part of the New Dutch Water Line to repel potential attackers. It was positioned at a vulnerable point created by infrastructure projects of the 1930s.
The bunker reflects how the Netherlands combined military defense with water management in this era. Today, visitors can see how protection and landscape control were planned together.
The site is easily accessible and you can explore the exterior of the structure and study the surrounding defensive line. It is located about 550 meters north of the A2 highway and is also reachable on foot from other historic positions in the area.
This structure is one of roughly 40 bunkers of a specific type, all strategically placed to protect newly built railway lines. Few visitors realize that the defensive line was directly linked to water levels in the region.
