One of most beautiful and frequently visited castles in Germany is Schloss Benrath, a suburb of Dusseldorf. This lovely Baroque-style mansion was built between the years 1755 and 1770 for the Elector Palatine Theodor and his wife the Countess Elisabeth Auguste of Sulzbach. A visit to this castle is a much happier experience apparently than their marriage ever was. Theirs was a union based on political efficiency and not much else. Interestingly after twenty years of marriage they finally had an heir, but sadly the baby died the next day. After that the two lived apart until their deaths.
Living alone is not an easy task and made all the more lonely by doing so in a large multi-roomed castle. Schloss Benrath today is not a lonely place, but a promising tourist stop for happy travelers. I recommend it wholeheartedly!
