Frias castle origins date back to the 9th century, when Alfonso VIII repopulated the valley to reinforce the border between Castile and Navarre. The historic quarter preserves its medieval atmosphere, and urban layout.
On the tallest, most rugged end of a hill, the castle of the Duke of Frías stands, with its beautiful and well-kept mullioned windows, and 13th-century Romanesque capitals. In the city centre we must point out the church of San Vicente, whose Romanesque main front was taken to New York after the tower fell in 1904, and the convent of Santa María de Vadillo, founded at the beginning of the 13th century.
Near the town, crossing the Ebro river, we see a gorgeous medieval bridge, with a defence tower that dates from the 14th century.
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.
