Secret places

The Secret places project is now in its 4th season.

The aim of the project is to help young people (aged 12 to 18) find out more about Luxembourg City through tours of various unusual attractions.

To join one of these tours, please contact the City of Luxembourg's Service Jeunesse (Youth Department) to sign up. Tour groups will be formed on a first-come, first-served basis. Tours are scheduled every 4 to 6 weeks and are completely free of charge.

The tours generally take place on Tuesday or Thursday afternoons, but a certain degree of flexibility is required, as days and times may change depending on the type of activities planned, the availability of “Secret Places” hosts and their conditions.

The tours last between 1 and 2-and-a-half hours. Their durations will be published in advance.


This year's tour dates and details will be published in due course.


All tours are conducted in the presence of City of Luxembourg Service Jeunesse staff, under the supervision and guidance of someone from the institution or place where the tour is taking place.

If you wish to join one of these tours, please sign up with the City of Luxembourg’s Service Jeunesse et Intervention Sociale (Youth and Social Intervention Department). Please note that there are a limited number of places available for each tour.
To take part in one of the activities, send an email to

N.B.  As places are limited, requests will be processed in order of submission. Tour members will be sent a confirmation e-mail.
Requests will be processed on a first-come, first-served basis.

Examples of tour sites

Most of the tour sites are well-known, but normally closed to the general public. The tours provide a unique opportunity for participants to discover what goes on behind the scenes.

Below are a few examples:

  • Notre Dame Cathedral is one of the main features of our cityscape. We’ve all heard the cathedral’s bells, but how many have climbed the stairs of the bell tower and actually touched them?
  • The Kockelscheuer skating rink: everyone has been there at least once, but do you know how the ice is made?
  • The Muhlenbach caves: who is brave enough to enter these 50,000-year-old caves? Accompanied by an experienced guide from the local caving club, participants will discover the deepest, darkest secrets of this small but impressive cave.
