Step back in time and explore Luxembourg's hidden secrets! The Casemates du Bock and de la Pétrusse open their secret passages for a unique adventure beneath the city, and the cherry on the cake: they're open ALL year round (except December 25th and January 1st).

A labyrinth of underground galleries, legends, fascinating stories AND a breathtaking view of the old town! A fascinating dive into the history of a once impregnable fortress! And that's not all... The Casemates de la Pétrusse offer an even more immersive experience, with light displays, projections and interactive animations. Between heritage and modernity, this visit promises to be as fun as it is instructive.

To explore these impressive underground galleries, you have two choices: you can visit them on your own or in the company of a super guide! Spend an hour exploring the passages that witness the fortress-town's past, and discover the many architectural and historical facets of this spot.

An unmissable experience that's fun, captivating and 100% wahouuuuh!
