The castle was constructed around 1100 as a castle by the cadet branch of the House of Wittelsbach. In 1182, the last Count of Dachau, Konrad III, died without issue and Duke Otto I of Bavaria took possession of it shortly thereafter. The original castle was demolished between 1398 and 1403. In 1467 Sigismund, Duke of Bavaria resigned and then kept only Bavaria-Dachau as his domain until his death in 1501.
