Luxembourg City

Luxembourg City lies on the southern part of the Luxembourg plateau, a large Early Jurassic sandstone formation that forms the heart of the Gutland, a low-lying and flat area that covers the southern two-thirds of the country.

In the Roman era, a fortified tower guarded the crossing of two Roman roads that met at the site of Luxembourg city. Through an exchange treaty with the abbey of Saint Maximin in Trier in 963, Siegfried I of the Ardennes, a close relative of King Louis II of France and Emperor Otto the Great, acquired the feudal lands of Luxembourg. Siegfried built his castle, named Lucilinburhuc ("small castle"), on the Bock Fiels ("rock"), mentioned for the first time in the aforementioned exchange treaty.

Luxembourg City is a commune with city status, and the capital of the Grand Duchy of Luxembourg. It is located at the confluence of the Alzette and Pétrusse rivers in southern Luxembourg and contains the historic Luxembourg Castle, established by the Franks in the Early Middle Ages, about which the area grew up.
