But you have an unlikely ally. This self-guided outdoor mystery game takes you through 13 real locations across the Belgian capital.

Download the free Questo app, start at Grand Place, and begin anytime. No guide, no booking required.

Follow cryptic clues from the UNESCO-listed Grand Place to the Hotel Amigo (where Karl Marx was imprisoned), the square where Jacques Brel is immortalised in bronze, the Royal Galleries (site of the first Lumiere brothers screening in Belgium), and the square where Einstein and Marie Curie once met. At each stop, a puzzle unlocks the next chapter.
