Last week we looked at Baarle-Hertog, which consists of a number of Belgian enclaves located across the border in the Netherlands. If it seemed that no other Flemish municipality could be more complicated, think again. This week we look at Voeren, a Flemish municipality that belongs to the province of Limburg. However, geographically it is completely isolated from the rest of Limburg. It's actually surrounded by the Netherlands and Wallonia.
