"Amazing place !"
Nicolas van de Walle
"There is no gate on one side so you can get in there. I really liked it. Long underground corridors. It is better to have a good flashlight with you if you want to explore the tunnels). Interesting territory. Now they have made a Land Rover test site there, and fenced the territory."

"This is a beautifully preserved fort. It's quite a feat to walk through the corridors. It gives a good impression of the complex structure. Although there are some deep shafts, you can navigate the fort safely with a few lamps. The lower corridor, which once served as an air supply, is now completely flooded. We were still able to walk a good 300 meters of the 900 meters."
