An unnamed farmer moved a border demarcation stone that separates France and Belgium

It wasn’t an ordinary rock

That’s what a Belgian farmer learned after he moved a sizable stone that constantly disrupted his tractor’s path. But, it turned out the rock was actually a marker that served as a divider for France and Belgium, according to the BBC

Moving the stone marker 7.5 feet reportedly made France smaller and Belgium larger. The shifted border was first noticed by a local who explored the boundary earlier this year.

The two areas that are directly affected by the moved stone are the French commune Bousignies-sur-Roc and the Belgian municipality Erquelinnes, which are both rural lands located south of the North Sea.
