Tjølling and Kaupang were one of the oldest and biggest Viking settlements in Scandinavia. The Tjølling Church, built in the early 12th century, had a connection to the Viking trading centre and ancient Huseby farm. The church was damaged by fire in 1360 and rebuilt. A rare earthquake damaged it again in 1750s. The restoration took place in 1762-1767 and the appearance was modified to the Rococo style. The altarpiece and pulpit date from the 17th century.
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.
