In Harderwijk, we built the towers and installed various obstacles, bridges, and the massive maze for Fort Vertier. Fort Vertier is a 3D labyrinth, a fun activity for children aged 6 to 12 featuring four towers and a large maze. The goal of the game is to reach all the towers as quickly as possible via a specific route through the maze, climbing and scrambling toward the suspension bridges. Fort Vertier is an activity where children can burn off their energy in a fun way. Additionally, it is educational, and the competitive element makes the children even more enthusiastic.
