The fortified town of Rello still maintains the original defensive walls and castle that were used as protection against civilisations that came from the south following the Douro River. It is the best-preserved walled enclosure in the province.
You can go inside through either one of the two gates located on the sides of the castle. The castle is protected by a fortified enclosure with circular and quadrangular towers that have elbow openings. The upper part of the towers are crowned with 15th-century machicolations and you can still see some remains of the keep, a water pool and a wall of the gate that separated the castle from the rest of the town.
In the outer enclosure, there are still gunboats in the lower section that were used for artillery.
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.
