Blackhammer Chambered Cairn is a Neolithic cairn on Rousay. It is thought to date from around 3000 BC. The structure is a typical stalled cairn, with an interior divided into seven compartments by pairs of upright stone slabs. The cairn has a modern roof, as the cairn originally was only a few feet high. Access is by a hatchway and ladder in the roof, as the original entrance was sealed. There have been finds of bones and pottery in the cairn.
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.
