Wilhelmsbad Castle (Ruin) (Hanau)

Built between 1779 and 1781, the castle, in the immediate vicinity of the former spa, is surrounded by gnarled oaks on an artificial island. It is one of the earliest and thus most significant examples of a pseudo-medieval park castle with a ruinous character on the European continent.
