The so-called Powder Tower (Kruttornet) is the oldest monument in Visby. It was built in the 12th century to protect the harbour. There was initially no door in the tower, but only a small entrance in 10 meters high. Defenders used ladders to climb up to the entrance. Today 25 meter high tower is open to the public in summer season.
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.
