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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
