History+
The origins of the castle can be traced back to the early 15th century, when the square keep, featuring mullioned windows, was built or rebuilt. Of the original surrounding walls, only a round tower, a section of wall, and a water-filled part of the moat remain today. From the same era are a round staircase tower with small square windows and a southeast-facing gateway to the courtyard, whose lintel is decorated with an escutcheon. A new residential building was constructed in the 17th century and expanded in the 19th century with a Neo-Gothic staircase tower.
