Three Country Cairn
Finland
It’s got a different name in Finnish, Swedish and Norwegian, but they all translate to the same thing – Three Country Cairn. It’s got the name because it’s literally the point where all 3 countries meet.
It was erected in 1897 after decades of boarder disputes and skirmishes. It took a lot of negotiation to decide that the three countries met at a certain point in the middle of a lake, and a stone was placed there to remind everyone where their country ended.
In the middle of the ass end of nowhere, Scandinavia.
