Discover all the games at Fort Vertier

Leave the couch and screens behind for a while. At Fort Vertier, kids step right into the game themselves. Inside and around a large Roman 3D maze, they run, climb, explore, and scan their wristbands to earn points.

There are several games to play. Test your speed in the Tower Game, solve Roman riddles in the Board Game, or search for Felix the Roman in the Scavenger Hunt. Everything takes place outdoors, with plenty of room to move around, try again, and beat the high score.

What game are you playing?

At Fort Vertier, you don’t just follow a set route. Children receive instructions, get some help getting started, and then play various games in and around the fort. We tailor the order of activities to the moment and the group.

Every game feels different. Some are all about speed, others about thinking strategically or searching carefully. But one thing always stays the same: kids are out and about, getting active.

Game 1

Tower Game

Reach the towers in the correct order.

The Tower Game is all about speed, navigation skills, and making smart choices. Children scan their wristbands, find the right tower, and scan again there. Then they move on to the next tower and try to beat their previous time.

Game 2

Board game

Solve Roman riddles.

There are Roman riddles on two levels around the fort. Children choose the correct answer and then look for the corresponding symbol inside the fort. This way, they run back and forth between thinking, searching, scanning, and playing.

Game 3

Search Game

Where is Felix the Roman?

Felix the Roman has hidden himself in various spots throughout the fort. Children are given a map and search for Felix in all sorts of situations. Found him? Then they cut out the figure, and the search for the next one can begin.

What is Fort Vertier?

Fort Vertier is a large Roman-style 3D maze in Harderwijk. Here, children play outdoor games. No benches, no screens—just running, scanning, searching, climbing, and scrambling.

The fort consists of several paths, entrances, floors, and towers. Children are constantly moving in and around the fort. Sometimes they look for the quickest route to a tower, sometimes they solve a Roman riddle, and sometimes they search for Felix the Roman.

How the wristband works

In several games, children use a wristband. Before entering the fort, they scan their wristband. Then they find the right tower, entrance, or spot in the fort and scan it again.

They can see right away on the screen if they’re in the right spot. In the Tower Game, they can also see their time. Is it wrong? Then they keep looking. Is it right? Then on to the next challenge. That’s how Fort Vertier feels like a real game—but outdoors.

"The 7- and 12-year-olds kept themselves entertained for two hours with the three different types of games they could play. It was especially nice that the questions they were given took their different ages into account."

"This was our first time here, and we weren't quite sure what to expect, but the friendly staff member explained everything clearly, and then the fun could begin! We got to explore the inside of each tower, and then the kids played the next game—this was also clearly explained, and the kids had the absolute best time! At the end, they got a super cool Fort Vertier tattoo, and they had a fantastic adventure! Thanks!"

"My daughter and I really enjoyed your beautifully designed maze. It was a bit tricky for adults to navigate at times, but we found it all quite amusing. It helps to keep your wits about you."
