The spectacular Kallio church, designed by Lars Sonck and built in 1908–1912, represents the Finnish national romantic school of architecture, as well as a change to Art Nouveau. The bells of the tower play a melody composed by Jean Sibelius. Inside the church are numerous interesting details such as a crucifix and relief made by sculptor Hannes Autere.
In the beginning of independent Finland Tolstoyan movement took the church as their base and proclaimed pacifism there. During World War II the church tower was one of Helsinki's air control points. In good weather, you can see Estonia from the tower.
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
