During the period of National Romanticism architects turned against the international tendencies of the dominating style, the Historicism. Instead, they tried to cultivate a specific Nordic style, seeking inspiration in old building types such as stave churches and Romanesque stone churches.
Windows of the style period are often decorated and adorned with symbols from Nordic mythology. The City Hall of Copenhagen serves as a premium example of National Romanticism in Denmark, with lead light windows set in Gothic sandstone tracery and decorated with reliefs of Odin's ravens.
