Schloss Wickrath was built between 1746 and 1772 by count Wilhelm Otto Friedrich von Quadt. The Baroque palace was built to the foundations of late medieval water castle. The original castle was demolished in 1859 by the Prussian administration. The current ensemble of buildings in the park, the Baroque west and east wing and the so-called Landstallmeisterhaus, the residence of the former stud master were built in 1875. The park has the shape of a coronet of a count of the Holy Roman Empire.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
