The medieval stone church of Ås date back to the 12th century. It is the only church in Öland where the tower is located in the east side. The church was enlarged in 1770 and the interior is mainly from the 18th-19th centuries. The pulpit is very unusual; this nineteenth century work is directly above the altar, an arrangement rarely seen in Swedish churches. The church is long established as a landmark for seafarers. During the nineteenth century the tower was rebuilt to incorporate a lantern, so that it doubled as an early lighthouse.
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.
