Frösunda Church was built in the 15th century to the site of older wooden church. The baptismal font of sandstone dates from the late 12th century. The altarpiece dates probably from the 15th century and is carved in Germany. The rococo style pulpit was carved by Magnus Granlund in 1759.
The external bell tower was mentioned first time in 1631. There is also a 11th century runestone outside the wall.
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.
