What is the fort used for nowadays?
In 1963, the University purchased the fort from the Ministry of Defence.
The same year, they started constructing a rock garden on top of the fort.
Have a guess how many mountain and rock plants grow on the fort now?
Over 1,600 from all over the world, but particularly from the Alps. This rock garden is the largest in the Netherlands.
Why does the fort serve as a paleomagnetic laboratory?
To avoid any sparks near the gunpowder, the gunpowder storage room at Fort Hoofddijk was constructed without any metal. The perfect place for researching magnetic phenomena!
