Wiltz Castle dates back to 1573. In 1388, the French attacked the town and burnt the castle down but it was soon repaired. The round Witches' Tower to the east of the gardens is the oldest part remaining. Today's Renaissance style castle was completed in 1727. It was acquired by the state in 1951 for use as a retirement home. It is now known for hosting an annual open-air music festival. It also houses the National Museum of Brewing Art.
