[1] 'Nil' is the name of a small river, along whose valley the various areas of settlement (Nil-Pierreux, Nil-Saint-Vincent, Nil-Saint-Martin) lie.
It was used until 23 June 1946[2] and today is a listed building (monument classé).
The Institut Géographique National, the Belgian national cartographical service, calculated that the geographical centre of Belgium lay in Nil-Saint-Vincent.
