The town received its name, according to old sources, when Charlemagne in the late 8th century resettled Saxons, in order to bring them under his control. One of the centre of these settlements was in the area of Diekirch. In order to convert the pagan Saxons to Christianity, a church was built, which gave the settlement its name: Diet-Kirch (people's church).
In the 14th century, Jojn, the blind king of Bohemia, fortified it, surrounding the place with a castellated wall and a ditch supplied by a stream. It remained more or less fortified until the beginning of the 19th century when the French, during their occupation, levelled the old walls and substituted avenues of trees.
In the course of extensive excavation in the 1960s, it was shown that the St. Laurence church is a Roman building. In the early 20th century, wall ruins and mosaics were being found north of the town centre. Archaeological investigations in 1992-1993, 1999 and 2008 enabled the reconstruction of a large Roman villa, which extended over all the land of the medieval town and was abandoned in the early 5th century.
Diekirch was the first town in Luxembourg to have a pedestrian zone, in 1977.
