The church of Vimpeli was completed in 1807, but not inaugurated until 1811. The exterior of the wooden church is unique: it has twelve corners and looks like round church. The architect was Jacob Rifj, who was inspired of Pantheon temple in Rome. The interior is also interesting. The altarpiece was painted by R. W. Ekman in 1872.
References: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.
