The oldest parts of Trosa Country Church (lands kyrka) were built in the 1200s. The sacristy was added later in the 1300s, vaults and tower in the 1400s. The strong tower may have had a defensive purpose. In 1773 church was badly damaged by fire and restored. The altarpiece is painted in Netherlands in the mid-1500s. The pulpit was made in Stockholm in 1706. The crucifix dates from the end of 1200s and wooden sculpture of St. Anne (North Germany) from 1400s. The font is made in Gotland and is as old as the church itself.
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.
