The commune of Diekirch, the source of the popular Diekirch beer, is located on the Sure river, on the border between the Gutland and Oesling regions. Diekirch is also known for St. Laurences Church, one of the oldest surviving Christian religious sites in Luxembourg. It has an excavated gravesite from the Merovingian era, circa 700 CE, which was discovered during renovations in 1961. An even older religious site is the Deiwelselter, or Devils Altar, which is thought to be a Celtic sacrificial altar.
The N7 and the N17 roadways intersect in Diekirch. It has a population of 6,700 residents.
