The Orthodox Church Museum, established in Kuopio in 1957, derives from the Collection of Ancient Objects founded at the Monastery of Valamo in 1911. Most of the exhibits, which consist mainly of icons, sacred objects and liturgical textiles, are from the monasteries and congregations of Karelia: a region in southeast Finland that was partially ceded to the Soviet Union in connection with the Second World War. Objects in the museum are mainly from the 18th and 19th centuries.
In addition to the permanent exhibitions, the museum offers yearly seasonal exhibitions. These theme-based exhibitions are aimed to introduce the variety of ecclesiastical art of eastern Christian Church. The virtual exhibition is built in accordance to the physical frames of the museum building: icons and sacred objects are displayed upstairs, liturgical textiles downstairs.
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.
