• From 1995 to 2004, Viroinval was the location of the
geographical centre of the European Union, at coordinates in Oignies-en-Thiérache, and a monument there records that finding. On May 1, 2004, the EU expanded from fifteen states to twenty-five, and the geographical centre of the union moved eastwards to the village of
Kleinmaischeid,
Rhineland-Palatinate,
Germany. On 1 January 2007 it shifted even further south-eastwards. • The tourist steam train line Mariembourg–Treignes has most of its stations in villages of Viroinval: Nismes, Olloy-sur-Viroin, Vierves-sur-Viroin, and Treignes. The latter village has a relevant museum. == See also ==
