The boundary stone was in the way of his Belgian farmer accidentally moves French border - BBC News
"He made Belgium bigger and France smaller, its not a good idea," David Lavaux, mayor of the Belgian village of Erquelinnes, told French TV channel TF1. That sort of move caused a headache between private landowners, he pointed out, let alone neighbouring states.
The border between France and what is now Belgium stretches 620km (390 miles). It was formally established under the Treaty of Kortrijk, signed in 1820 after Napoleons defeat at Waterloo five years earlier. The stone dates back to 1819, when the border was first marked out.
Local Belgian authorities plan to contact the farmer to ask him to return the stone to its original location. If that does not happen the case could end up at the Belgian foreign ministry, which would have to summon a Franco-Belgian border commission, dormant since 1930.
