Trematon Castle was the caput of the feudal barony of Trematon. It overlooks Plymouth Sound and was built probably by Robert, Count of Mortain on the ruins of an earlier Roman fort: it is a motte-and-bailey castle and dates from soon after the Norman conquest.
Trematon Castle, like Restormel Castle, has a stone shell keep raised on an earlier motte. Although in ruins, much of the Norman walls remain standing, so that the original form of the Castle and keep are clear. The internal diameter is approximately 21 metres. A rectangular gatehouse, built in 1270, has two floors and a portcullis. Both are in good condition. The castle is currently open to the public.
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.
