Underground treasure hunt at the Coudenberg

Location:
Coudenberg
Place des Palais 7 - 1000 Brussel (entrance via the BELvue Museum)
Period:
Thursday 1 January 2026 - Thursday 31 December 2026
Category:
Youth

From Tuesday to Sunday at the Coudenberg. For children from 5 to 8 years.

The Coudenberg is the former palace of Emperor Charles the Fifth. The search for the collar of the Golden Fleece in the underground relics is an activity for families.

How does the search go?

Every child receives a backpack with the equipment to complete missions (treasure map, fancy dress, puzzle, flashlight,...). Every mission gives an indication to find the password that will allow them to reach the treasure chest (where the famous collar of the golden fleece is).

The children receive a little gift at the end of the game.

Duration: 1h to 1h30
