Poilvache Castle is a ruined medieval castle in the Walloon municipality of Yvoir, overlooking the village of Houx from a clifftop on the river Meuse.
The present ruins date from the 15th century, although there has been a fortification on the site since the time of Charlemagne. The Liégeois town of Poilvache, a thriving walled town, protected by a castle, with a prosperous economy and its own mint, and allied to Duke Philippe the Good, virtually ceased to exist following its 1430 siege by the rebellious Prince-Bishop of Liège, Jean de Heynsbergh, and an estimated army of 30,000 Liégeois, Dinantais and Hutois. The Dinantais besiege Montaigle Castle in 1465 for the same reasons but Montaigle was destroyed in the 16th century by the army of Henri II of France.
From the top of these rocks it is possible to see the isle in the river where the German army and its armoured divisions crossed (in the North of the isle), the river Meuse on 13 May 1940.
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.
