Utrecht Monster Mystery: Outdoor Escape Game

Overview

Your museum sent you to Utrecht to investigate monster sightings. You're skeptical, until your first witness describes a cockatrice, a medieval military order still active in the city, and a woman who bricked herself inside a church wall.

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.

Discover stories most visitors miss: a cathedral that vanished in a single storm, the only Teutonic Order still active in the Netherlands, and a UFO on a building made from 22 million bricks.
Perfect for couples, families, or curious explorers. About 70 minutes, 7 stops through Utrecht's medieval center.
