William IV of Bavaria and his son Albert V ordered the construction of a Renaissance style four-wing palace with a court garden on the site of the old castle. The new building was designed by Heinrich Schöttl; construction began in 1546 and was completed in 1577. It later became the favoured residence of the rulers of Bavaria. Also, close to Dachau Palace was the Schleissheim Palace that started out with a renaissance country house (1598) and hermitage founded by William V, Duke of Bavaria.
