In 1910 during the restoration of Angerdshestra church 30 old pergaments were found revealing that the old church was inaugurated in the 13th century. Today documents are located in Stockholm Historical Museum. The current church was made of wood in 1669 to the site of medieval church. It was enlarged and restored in the 18th century. The oldest artefact is a wooden sculpture of St. Anne, dating from the 15th century. The altar was probably painted by Johan Kinnerus between 1716-1717.
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.
