Leeuwarden — Decode Mata Hari's Espionage

🎭Your Mission

You are a secret service agent, tasked with reconstructing Mata Hari's journey before her downfall, in Leeuwarden, 1917.

Your mission begins in front of the Kanselari

Delve into the alleys of Leeuwarden, the capital of Friesland, and decode the mysteries surrounding the life and alleged espionage of Margaretha Zelle, the famous Mata Hari.

« The heaviest burden weighs least on me »
Motto of the city of Leeuwarden (Frisian)

The story that haunts this land

Your investigation begins at the Kanselarij, a Dutch Renaissance style rijksmonument built between 1594 and 1596, which served as a courthouse until 2011. Its facade, adorned with allegorical sculptures, rises 25 meters high and was a landmark for Frisians. From there, you are launched on the trail of Margaretha Zelle, born on August 7, 1876, in Leeuwarden. Your first crucial stop is Mata Hari's Geboortehuis, at number 30 Grote Kerkstraat. This typical 19th-century Dutch house, where Mata Hari lived until she was 6, now bears a commemorative plaque. In 2026, it will be a central point of the '150 years Mata Hari' tourist route, celebrating her legacy in the capital of Friesland.

Less than 200 meters from the Geboortehuis stands the Grote of Jacobijnerkerk, a Gothic church built between 1480 and 1485, whose tower reaches 61 meters. This rijksmonument number 859, Leeuwarden's main Reformed church, houses a Christian Müller organ dating from 1730. The contrast between the simplicity of the birthplace and the grandeur of the church illustrates Mata Hari's humble origins in this historic district. Your journey then takes you towards the Oldehove, Leeuwarden's emblematic tower, whose construction was halted in 1533 due to lack of funds, leaving it incomplete at 40 meters and leaning 2.1 meters. This rijksmonument number 18548 is visible 2.5 km around the center and its Mata Hari visitor center, located opposite on Heer Ivostraatje, reinforces its connection to the spy.

The Fries Museum, founded in 1877, is an essential stop. This Neo-Renaissance building from 1902-1903, designed by A. Wigboldus, hosts the permanent exhibition 'The Lifes of Mata Hari', dedicated to Margaretha Zelle's four lives. With a collection of 500,000 Frisian objects and 3,000 m² of exhibition space, this museum, located 800m from the Kanselarij, immerses you in the cultural and historical context of Friesland that shaped the young woman. Here, you discover valuable clues about her identity and evolution, crucial to your investigation into her unique journey and the city of Leeuwarden.

The Prinsentuin, a baroque garden created in 1680 for stadtholder Henri Casimir II, offers a strategic break. Its 2 hectares of canals, statues, and 18th-century orangery, renovated in 1997, are the scene of concerts and temporary Mata Hari exhibitions. This site, 600m from your starting point, allows you to reflect on the secrets that gardens hide. Finally, you reach the Waag, a weighing house built in 1598 on the Marktplein, 400m from the Kanselarij. This Renaissance-style rijksmonument, with its 28-meter wide facade and Frisian gables, was used until 1920 to weigh spices and fabrics. Its 1691 clock watched over transactions, just as it seems to watch over the city's secrets.

As you complete your journey at the Waag, you have traversed the history of Leeuwarden, from the residences of stadtholders like Willem Lodewijk van Nassau to the heart of its commerce. Each rijksmonument, each street has revealed a facet of Mata Hari's life and Frisian identity. You have explored Leeuwarden's historic center, from Grote Kerkstraat to the Prinsentuin, discovering sites that, beyond their beauty, tell a story of ambition, mystery, and heritage. This immersion offers you a deep understanding of the city and its connection to one of the most enigmatic figures of the 20th century, whose memory is kept alive by Frisian heritage and initiatives like '150 years Mata Hari' in 2026.

Frequently asked questions

Q01Is Leeuwarden — Decode Mata Hari's Espionage similar to a treasure hunt?

Same spirit: search, deduce, find. But here the "treasure" is a full story to piece together in eight stops. Each stop gives you a fragment of the final code. Eight fragments later, you've cracked it.

Q02How far do you walk in Historic center of Leeuwarden?

Usually 2 to 4 km of total walking, within 1.5 km as the crow flies from the start point. The route is designed to be walkable at a relaxed pace, no public transport needed.

Q03Can we do Leeuwarden — Decode Mata Hari's Espionage as a family with kids?

Yes, from age 6 with an adult reading puzzles aloud, and from age 12 on their own. Kids love the "find the camera clue" part — it's very visual, gets them genuinely involved.

Q04What if we get stuck on a puzzle?

Three hint levels per puzzle, with a small increasing time penalty. If truly stuck after level 3, you can skip the step (45-min penalty). The point: nobody stays blocked and goes home frustrated.
