Benelux is a small geographical entity, which encompasses the countries Belgium, the Netherlands, and The Grand Duchy of Luxembourg. Although the Benelux countries cover a small area, there has been interest there for magnetic observations since early on. As a result, many observatories have been created by the Benelux countries at home and abroad. Luxembourg has no observatory of its own, onldy field geomagnetic measurements have ever been made (Flick and Stomp, 2002).
