Lenzburg Castle

Lenzburg Castle (German: Schloss Lenzburg) is a castle located above the old part of the town of Lenzburg in the Canton of Aargau, Switzerland. It ranks among the oldest and most important of Switzerland. The castle stands on the almost circular castle hill (altitude: 504 m), which rises approximately 100 m (330 ft) over the surrounding plain but is only about 250 m (820 ft) in diameter. The oldest parts of the castle date to the 11th century, when the Counts of Lenzburg built it as their seat. The castle, its historical museum and the castle hill with its Neolithic burial grounds are listed as heritage sites of national significance.

The prominent hill was already a settlement site in prehistoric times. For example, in 1959 a Neolithic gravesite was uncovered in the carpark. There have also been small discoveries from the Roman and Alemannic eras.

A legend tells that there was once a dragon living in a cave in the hillside, who was defeated by two knights, Wolfram and Guntram. The grateful people made the two Counts of Lenzburg and gave them permission to build a castle on the hilltop.

A charter dated 1036 names one Ulrich, Count of Aargau. He was the Emperor's Vogt in Zürich and overseer of the abbeys of Beromünster and Schänis. The first definite record of the existence of a castle dates to 1077: Ulrich's grandson, also Ulrich, had taken the emperor's position in the Investiture Controversy and imprisoned two Papal legates for half a year. At that time the Counts of Lenzburg were among the most important feudal lords on the Swiss plateau and maintained close connections to the emperor.
