The rock on which the first castle stood, founded in 963 by Sigefroy (Sigfried). It is tied to a number of other remains of the old fortifications. Among others, the famous fortress builder Vauban built much in the city.
The Bock is a promontory in the eastern corner of Luxembourg City's historical upper town, the Ville Haute. It was here that Count Siegfried built his Castle of Lucilinburhuc in 963, providing a basis for the development of the town that became Luxembourg. Over the centuries, the Bock and the surrounding defenses were reinforced, attacked, and rebuilt time and time again, as the armies of the Burgundians, Habsburgs, Spaniards, Prussians, and French vied for victory over one of Europe's most strategic strongholds, the Fortress of Luxembourg. Warring did not stop until the Treaty of London was signed in 1867, calling for the demolition of the fortifications. Ruins of the old castle and the vast underground system of passages and galleries known as the casemates continue to be a major tourist attraction.

A network of underground fortifications, built in the 18th century. The fortifications and environs are recognized as a UNESCO World Heritage Site.
The Alzette, thought it is very small now, because the sandstone of the area is very soft, it dug out a huge valley. This is called the Ville Basse and is a spectacular area particularly the Grund (Statgrond) which is well worth the time to take a stroll around. The old fortress surrounded this valley. The Venceslas walk (named after Venceslas, Czech king and count of Luxembourg who built much of the fortresses around) leads along the fortresses, protecting the city on one side (and now forming one of the most spectacular "balconies", the Corniche) and the fortress of the Raam plateau on the other.
This church took on its present form in 1688, but was probably built in the early 14th century. It was restored during 2003 and 2004.
