Explore the exciting old fort island at GeoFort. Plenty of experiments await both inside and outside: wander the dark subterranean tunnels, make your way through the maze or use the lift to descend 6,000 kilometres into the earth. Use the maps to find your way around the virtual Minecraft world or visit the virtual sandpit, where you can make a volcano erupt! Feel like having a break? Our pancake restaurant, De WereldPan, has an extensive food and drinks menu.
The Goejanverwelle lock and the Enkele Wiericke lock on the Hollandse Ijssel played a key role in the Disaster Year. Together with the lock at Nieuwerbrug on the Oude Rijn, they formed the inlet to the Langeweide polder, which was the narrowest section of the Waterline. The locks were opened on 17 June 1672 – just in time to halt the advance of the French, who had already captured Oudewater and marched right up to the edge of the hastily flooded Waterline. With great promptitude, the commander of the garrison at Goejanverwelle, the Count of Horn, gave the order to raise sconces and fortifications to defend the locks. For the moment, the Waterline was safe!
