The octagonal wooden Bakke Church was built in 1715 and designed by the architect Johan Christopher Hempel. It is the oldest building in the Bakklandet area of Trondheim since it was the only building that was spared during the Swedish siege of 1718. After World War I, the Innherredsveien road (the old European route E6 highway) was widened and upgraded and the church was located too close to and the church became a major traffic obstruction. This led to plans to demolish the church, especially after the opening of the new Bakke bridge in 1927. It was decided to save the church, so the whole church was jacked up with a jack and moved several feet to the side in 1939. Then it was restored and consecrated again in 1941.
Although it is part of the established (Lutheran) Church of Norway, Bakke Church is also home to Trondheim's small Eastern Orthodox Church congregation, who do not possess their own church building.
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.
