Guided tour of Maastricht Caves, Fort Sint Pieter, Casemates and NATO Headquarters
Maastricht Underground offers a huge choice of underground adventure. Below, we briefly explain the difference between the locations and what can be seen in the different caves Maastricht. Finding it hard to choose? A combination of tours in Maastricht is possible.
Caves of St Pietersberg hill (North Caves and Zonneberg caves)
The Caves of Sint Pietersberg hill house a treasure trove of history, art and adventure. The underground maze consists of two parts: North Caves (Grotten Noord) and Zonneberg Caves (Grotten Zonneberg). These tours can be booked and visited as separate locations.
North Caves
The Caves North are a kind of magical underground world filled with unique charcoal drawings, inscriptions and paintings. Unlike the Zonneberg Caves, Caves North is a system with more differences in corridor heights (low and high). During World War II, the caves were also used differently. Caves North were used as a hiding place for Dutch most famous works of art.
In Caves North you can take a guided tour that takes you to the mysterious "Kluis" (vault). During World War II, as many as 780 art treasures were kept safe here. It is a place steeped in history and stories.
Zonneberg Caves
Zonneberg Caves is a spacious and structured system of corridors. On a guided tour with an experienced guide, you walk past the many names and drawings in the walls, which come to life thanks to the guide's stories. Especially when you consider that the vast corridors of this system were used as an air-raid shelter for the civilian population during the Second World War.
Did you know that you can also visit the Zonneberg Caves by scooter? Together with a professional guide, you will silently glide through time. The advantage of visiting by scooter is that you can go deeper into the cave and discover even more!
Vault and Museum
The North Caves were used as a hiding place for the Netherlands' most famous works of art. At the time, these were stored in a special vault (known as "Kluis"). At Zonneberg Caves, you have the option of choosing a guided tour with or without a visit to an underground Museum. A highlight of the visit to Zonneberg Caves is the life-size replica of Rembrandt's "The Night Watch", an impressive creation that you can admire in this unique setting.
Fort Sint Peter
Fort Sint Pieter is an imposing fortification that towers high above the city. Originally built to protect Maastricht from enemy raids, this fortress now offers visitors the chance to discover the history of the fort and the city. You can take guided tours that take you through the corridors and rooms of the fort, and you will be amazed by its strategic construction and breathtaking views from the ramparts.
Maastricht Casemates

Here you can be part of a fascinating guided tour and immerse yourself in the story of the fortifications and the historical events these corridors witnessed.
