A guided tour for visitors who have already taken a tour of the fort.
One Saturday each month, we organise an in-depth programme for enthusiasts. Each month features a different theme; the programme is repeated every three months.
The discovery tour concludes with the start-up of the nearly century-old Carels generator, the mechanical heart of the fort. This impressive 175 hp engine was installed in the late 1930s to supply the fort with essential electricity. After the Second World War, it fell silent… today, it is running once again.
The “Specialists” tour lasts 3 hours, from 10:00 am to 1:00 pm. Afterwards, with prior reservation, you may join the “Exterior Discovery Tour” or freely visit the barracks, the museum, and the immersive 180° experience.
The ticket remains valid for the entire day.
