The construction of Karlskirche in Vienna was a slow process, and it was finally opened after 25 years, in 1737.
The exterior of the church is a beautiful example of Baroque architecture, and it has not only a large dome but two tall columns flanking the entrance, which are decorated with spiralling images of scenes from the life of Saint Charles Borromeo.
On entering the church, let your gaze rise to the ceiling to admire the opulent frescoes in the cupola painted by Johannes Michael Rottmayr. The immense paintings show the glory of Karlskirche's patron saint in incredible splendor and beautiful colours.
One of Vienna's most important churches
Karlskirche is one of the city's most interesting churches, both inside and out. As well as its beautiful architecture and decoration, there's also a small museum and visitors can take the lift up to the top of the dome for a better look at the incredible frescoes.
