Location
Follow clues through 7 landmarks, from the Speelklok Museum to the Dom Tower, a Teutonic Knights compound, and a canal where a poem is carved into cobblestones one letter per week. Decode ciphers, question witnesses, and uncover the truth behind the Monster of Utrecht.
Download the Questo app, activate your quest with the booking code, and start playing at the Speelklok Museum. No guide, no schedule, explore at your own pace.
