Ballylahan Castle is a tower house and National Monument located in County Mayo, Ireland. It was constructed in 1260 by Jordan de Exeter, Sheriff of Connacht and was the ancient seat of the Mac Siúrtáin (MacJordans). The castle came under attack in 1316 by the King of Connacht, Fedlim Ó Conchobair and was almost destroyed.
The main entrance was in the east and it was flanked by two circular towers, of which only one remains. The entrance gives access to an irregular hexagonal bawn. There is evidence of buildings particularly against the western wall. The bawn has some good base-batter, particularly at the northwest corner.
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.
