Theme visit 120 mm artillery cupola

An exclusive and private visit with family, friends, colleagues, … after being welcomed by one of our passionate guides.

Due to the sometimes limited space of the visited areas and for everyone’s comfort, the number of participants is limited to a maximum of 10 persons per guide.

Before booking a theme visit, we recommend visiting the fortress individually or with a private ‘Family & Friends’ visit.

A theme visit can be booked every day of the year, except on Mondays and some closing days.
Reservations can be made up to 10 days before the desired visit date and up to 8 months in advance. Your reservation request will be confirmed by our secretariat as soon as possible.

This tour is not accessible for people with physical disabilities or wheelchair users.

This visit is not recommended for children under 12 years of age.

The 120 mm cupola is the only of its kind still remaining worldwide.

For connoisseurs: a visit to the largest artillery dome and, optionally, to an artillery casemate or defense bunker 4.

Discover what is under this imposing dome.
