The Founding of Luxembourg: Siegfried of Ardennes and Lucilinburhuc (963)

The recorded history of Luxembourg begins in 963, when Siegfried, Count of Ardennes, acquires Lucilinburhuc (modern Luxembourg Castle) through an exchange act with St. Maximin’s Abbey in Trier. This marks the foundation of what will become the Duchy of Luxembourg, a strategically vital state in medieval Europe.


The Acquisition of Lucilinburhuc

  • Lucilinburhuc, meaning "Little Fortress", was a fortified stronghold on the Bock rock, a naturally defensive site.
  • Siegfried of Ardennes, a powerful noble in Lotharingia, secures control of this strategic location through an exchange with St. Maximin's Abbey in Trier.
  • This acquisition lays the foundation for the development of a town and, eventually, a powerful state.

The Rise of Luxembourg

  • A settlement gradually develops around the fortress, growing into a center of trade and military activity.
  • Due to its strategic location between France, Germany, and the Low Countries, Luxembourg will become a highly contested region throughout medieval history.
  • Over time, the Counts of Luxembourg expand their influence, eventually becoming Dukes of Luxembourgand playing a key role in Holy Roman Imperial politics.
