Our Lady's Church (Vår Frue kirke) was erected around the year 1200. The victim of many fires, it was restored in 1739, but parts of the thick, solid walls of the Church are obviously much older. The first tower of the church was built around 1640, but the current tower was built in 1742 and the spire was erected in 1779. However, the eastern part of church (to the right in the picture) is identical to the 'Church of Our Mary' from the end of the 12th century.
The Baroque style altar dates from 1744 and rococo pulpit from 1771. There are also chandeliers from the 17th and 18th centuries. On the church wall you can see Runes which were carved into the stone 800 years ago.
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.
