Jättakullen stone cist.
On our way home we pulled over here, by the Jättakullen cist, for a cup of coffee and falu-sausage sandwich.
The cist is about 14m long and 4000 years old. (The picture shows one half of it.)
It is fascinating that these things were already one or two thousand years old when stonehenge and the pyramids in Egypt were rasied.
