If you plan to come in Belgium, you might have heard about Leuven and Louvain-la-Neuve or Louvain and Louvain-la-Neuve... But what is the difference ?
Leuven is a city located in the Flemish Brabant, in the west of Brussels at about 30 km from Louvain-la-Neuve. It is commonly called "Louvain" by the french speaking people of Belgium, a translation that often leads to confusion with the name of Louvain-la-Neuve.
For more information about the origin of the name Louvain-la-Neuve, refer to its history.
