What are these?



These stone blocks are located in the village of Kleingurmels, canton Fribourg. At first glance they look like tank traps, but that doesn’t make any sense, historically or by location. They are at the top of a small culvert so may be some form of erosion protection perhaps? There are also some in a flat field just outside Liebistorf, about 5 km away.

  1. It could be an anti-tank obstacle. There are lots of those with different styles around the country.

    Edit: I’ve looked it up and I’m pretty sure you’re looking at part of the “Panzersperre Biberenächer”

  2. they are called “Dragons Teeth” and are meant to be tank traps like you said, you can find them all over switzerland and in some parts of europe too. they were installed during ww1, upgraded during ww2 and the following cold war. i live not very far from kleingurmels and have driven past this installation countless times.
