Gothenburg Cathedral (Gustavi domkyrka or Göteborgs domkyrka) lies near the heart of the city. The cathedral was built in 1815 and replaced an earlier cathedral built in the 17th century. The architect was Carl Willhelm Carlberg. The cathedral is a fine example of neoclassical architecture. It is one of the top tourist destinations in the city. The Cathedral acts as a venue for a wide range of classical concerts and recitals, as well as hosting regular services.
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.
