Completed in 1868 in the Katajanokka district of Helsinki, the Uspenski Cathedral is the largest orthodox church in Western Europe. With its golden domes and red brick facade, the church is one of the most evident symbols of the Russian impact on Finnish history. In fact, the red brick of the exterior came from the Bomarsund fortress in Aland, which had been destroyed during the Crimean War in 1854. If you look up at the domes, you’ll count 13 in all. The domes of the cathedral are meant to represent Christ and the twelve apostles. Inside, the cathedral houses a vibrant display of icons and other traditional Orthodox decorations. One of the icons is even believed to work miracles.
