The Orthodox Church of Kotka, known also as St. Nicolas church, was built between 1799-1801 under the Russian order. It was designed in accordance with drawings by Jakov Perrin, architect of the St Petersburg Admiralty. The orthodox church is probably the oldest building in Kotka and one of the rare to survive a British bombardment of the town in 1855.
The church was built in Russian Neo-classicism style. Differing from a typical orthodox church in Finland, there are lot of sculptures inside the St. Nicholas Church.
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.
