Thurant Castle (Burg Thurant) was built in 1198-1206 by Heinrich Pfalgraf Guelphs. It was besieged in 1246-1248 during the war between Trier and Cologne archbishops. After the war the castle was interestingly divided to two parts, Trier tower and Cologne Tower. Both sides had a separate entrance and living buildings. In the 19th century the castle was left to decay, but restored in the 20th century.
References:Linderhof is the smallest of the three palaces built by King Ludwig II of Bavaria and the only one which he lived to see completed.
Ludwig II, who was crowned king in 1864, began his building activities in 1867-1868 by redesigning his rooms in the Munich Residenz and laying the foundation stone of Neuschwanstein Castle. In 1868 he was already making his first plans for Linderhof. However, neither the palace modelled on Versailles that was to be sited on the floor of the valley nor the large Byzantine palace envisaged by Ludwig II were ever built.
Instead, the new building developed around the forester's house belonging to his father Maximilian II, which was located in the open space in front of the present palace and was used by the king when crown prince on hunting expeditions with his father.
