From the 9th to the 14th centuries, many inhabitants of the Meuse, Moselle, Rhine, Flanders, Holland and Luxembourg areas left their homes to settle in Romania.
In Transylvania, which was founded in the 12th century by those settlers, called 'the Transylvanian Saxons', some people still speak a language very close to the Moselle Franconian spoken between the Moselle and the Rhine, and therefore very close to Luxembourgish.
Transylvania was attached to Hungary for centuries, and then to Romania after the First World War; a minority of its inhabitants can trace their roots back to Saxony, and the region is still officially bilingual (Romanian and German).
In view of the historic links which have left them with closely related cultures and traditions, Luxembourg celebrated the title of European Capital of Culture in 2007 together with the city of Sibiu, one of the main cities in Transylvania.
The 'Casa Luxemburg' was inaugurated in Sibiu in 2003. Casa Luxemburg houses the Institute of the Council of Europe's Institute of Cultural Routes, a tourist office, and a languages institute.
