The Suur-Savo Museum is located to a stone granary that was built in 1848 to serve as the parish of Mikkeli’s municipal granary. The building has been used as a museum since 1960. The permanent exhibition of the Suur-Savo Museum contains items from the peasant culture in Southern Savo and artefacts that depict the history of the city of Mikkeli. In addition, temporary exhibitions are held, usually in their own facilities, although sometimes they are arranged elsewhere.

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.
