Tours outside opening hours.

Between 1 May and 31 August, visits to the museum and tunnels are possible with a group.

From September 1 to December 19, only museum visits are possible and the tunnels are closed due to bat season.

We open our museum exclusively for your visit and organize a guide. The prices are therefore the same in both periods.
