Around the middle of the 10th century the allodium Meerssen was the property of queen Gerberga, the daughter of king Henry I. She was the spouse of Louis IV of France. In 968 she donated all her property to the abbey of Saint Remigius in Reims.
Meerssen is a founding member of the Douzelage, a town twinning association of 24 towns across the European Union. This active town twinning began in 1991 and there are regular events, such as a produce market from each of the other countries and festivals.[5][6] Discussions regarding membership are also in hand with three further towns (Agros in Cyprus, Škofja Loka in Slovenia, and Tryavna in Bulgaria).
