Lenzburg Castle

Lenzburg Castle is one of Switzerland’s oldest and most historic hilltop castles. For a thousand years it has played a part in many important events in politics and history across Europe. The early history of Lenzburg Castle belongs to the fog of time. Historians suggest it was originally built as a refuge fort in the Early Middle Ages. The “castellum lenciburg” is first mentioned in connection with Ulrich II, Count of Lenzburg, in a document dated 1077. When Ulrich IV died without heirs in 1173, his estate passed to the Holy Roman Emperor Frederick I, Barbarossa, and then to the Counts of Kyburg.
