Mystery Hunt at the CASTLE


Solve the murder at Kastellet in Copenhagen! You must crack codes, solve puzzles and uncover deception. Can you trust the other team members? Can they trust you?


You and your team must follow hidden clues that lead you around Copenhagen's colossal defences, Kastellet. While solving award-winning puzzles, you must also find out if there is a traitor in the group! Do you trust your team? Feel the tension and laughter rise - how well do you really know each other?

Do you need a digital detox too? Mystery Hunt is a 100% analogue experience with a human touch. Rediscover the joy of a beautiful, old-fashioned treasure map and leave your phones in your pockets while you solve the mysteries around you.

"We laughed, thought and played our way through the treasure hunt and had a blast"
