The experience

You start with a bump on your head and blue porcelain fragments scattered around you. Your tulip vase for the Royal family is gone, and you know who took it: the Pottery Pigeons. The Questo app guides you through Delft's canals and streets, dropping you at each of the 11 stops with a riddle to solve before you move on. The app tells you the story of each place as you stand there: the Eastern Gate, built around 1400 with its octagonal towers added in 1510, is the only city gate left in Delft. The Koornmarkt opens onto one of the city's famous canal streets. You pass the Gothic Saint Hippolytus Chapel and the Renaissance City Hall facing the Market Square, which measures 120 by 50 meters and is one of Europe's largest historic squares.

The walk takes you past the Vermeer Centrum, housed in the former guild hall where Vermeer himself joined the painters' guild in 1653. The Old Church, founded in 1246, grew into an impressive Gothic basilica over the centuries. At Museum Prinsenhof, you see the bullet holes still visible in the wall where William of Orange was murdered in 1584: a moment that changed Dutch history. The final stop is Windmill de Roos, built in 1679 and the only surviving mill of fifteen that once stood in the region. You explore at your own pace, so you can linger at any stop or move quickly through. There's no fixed schedule or group to keep up with.

One smartphone device works for up to three players, so a small group can share the game and solve the riddles together. If you want more people to play, you can buy extra tickets or opt for the full multiplayer experience at checkout. The app keeps track of your progress and your rivals' progress, so there's a race element: outsmart your competitors before the Royal family arrives. No prior knowledge of Delft or Dutch history is needed. The app teaches you as you go.

Top questions

How do I start the mystery quest and what do I need?

Download the Questo app on your smartphone before you arrive in Delft, then open it and start the quest anytime you're ready. One device works for up to three players, so you can share one phone or buy additional tickets if your group is larger.

What is the Eastern Gate and why is it the first stop?

The Eastern Gate is Delft's only remaining city gate, built around 1400 in Brick Gothic style and enhanced with octagonal towers in 1510. The other gates were demolished in the 19th century, making this the sole survivor and the natural starting point for your journey through the city's medieval past.

What happens at Museum Prinsenhof?

Museum Prinsenhof is an urban palace built in the Middle Ages as a monastery and later the residence of William the Silent. You'll see the bullet holes in the wall at the main stairs where William of Orange was assassinated in 1584: a pivotal moment in Dutch history that the app explains as part of your quest.

Can I do this walk with children?

Yes, infants and small children can ride in a pram or stroller, and the quest is suitable for all physical fitness levels. The riddles and story are designed for curious explorers of any age, and you control the pace entirely.

How long does the mystery quest take?

The walk takes around 90 minutes if you move steadily through all 11 stops, but you set the speed. You can spend more time at any location or move faster if you prefer. There's no fixed schedule.

What makes Windmill de Roos special?

De Roos windmill was built in 1679 for grinding corn and is the only surviving mill of the fifteen that once stood in the Delft region. The first mill on this site was mentioned in 1352, making it a landmark that spans centuries of the city's industrial history.
