During the Roman period, two main roads crossed the territory of the present city of Luxembourg; these two roads met at the place "Marché-aux-Poissons" (now a street and a neighborhood) dominated by a fortified tower. A castle was built here called "Lucilinburhuc" ("small castle"). In 963, this place became a property of Siegfried I, a close relative of the Emperors of Germany and Kings of France. Siegfried built a castle, not far from the "Lucilinburhuc" castle, on a rocky cliff called the "Bock" (). This place is now considered the birthplace of the city, the country and the nation.
