Uspenski Cathedral is an Eastern Orthodox cathedral dedicated to the Dormition of the Theotokos (the Virgin Mary). The cathedral was designed by the Russian architect Alexey Gornostaev (1808–1862), but it was built after his death in 1862-1868. It was made of bricks brought mainly from Bomarsund fortress in Åland which had been destroyed during the Crimean War in 1854.
Uspenski cathedral represents the Slavonic architecture, but the interior has a strong Byzantine influence. The cathedral has also several valuable icons. With its golden cupolas and redbrick facade, the cathedral is one of the clearest symbols of the Russian impact on Finnish history. It’s very popular tourist attraction with half million annual visits.
The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed.
