Kullerstad church is a whitewashed Romanesque stone church dating from the 13th century. It is known of two Gunnar's bridge runestones: according runes there was a man named Håkon who dedicated a bridge to the memory of his son Gunnar. The first runestone was found in the exterior wall of the church of Kullerstad in 1969 and is raised in the cemetery. The second stone was discovered in a church only 500 metres away and is also raised in the cemetery. The second stone informs that Håkon raised more than one stone in memory of his son and that the son died vestr or 'in the West.'
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.
