According the legend the first church in Selaön island was built by St. Olaf (Olaf II of Norway) in early 1000s. The current Ytterselö Church dates however from the 1100s. In the late Middle Ages it was changed as a square form hall church with vaults. The funeral chapel of Soop på Mälsåker family was added in 1650. The new choir was completed in 1728.
The beautifully carved triptych dates from c. 1500 and is made in Antwerpen. The crucifix was also made around 1500 and the pulpit around 1600. There is also an unusual tomb in the churchyard; The grave of Hans Åkesson Soop has four pillars and there is stone relief of Soop and his wife.
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.
