Arvfursten Palace (Arvfurstens palats) is located at Gustav Adolfs Torg in central Stockholm. Designed by Erik Palmstedt, the palace was originally the private residence of Princess Sophia Albertina. It was built 1783-1794 and declared a historical monument in 1935 and subsequently restored by Ivar Tengbom in 1948-52. Since 1906 the palace has served as the seat of the Ministry for Foreign Affairs.
The palace is facing the square Gustav Adolfs torg, with the Royal Swedish Opera on the opposite side. Located near the palace are the Sager Palace, official residence of the Prime Minister, and Rosenbad, official office of the government. The bridge Norrbro stretches past the Riksdag on Helgeandsholmen and further south to Stockholm Old Town and the Royal Palace.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
