Hejdeby Church was built in the 13th century, the choir and nave first (in late Romanesque style) and the tower later (showing early Gothic influences). The interior of the church is richly decorated with medieval frescos. These date from two periods: the oldest are from the 13th century and depict apostles, the crowning of Mary, and various saints. The other set of frescos date from the 15th century and depict scenes from thePassion of Christ. The church also has a triumphal cross dating from the early 13th century, a medieval baptismal font complete with its richly carved wooden lid, and an unusual medieval wooden bench. Other original furnishings are now in a museum in Visby.
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.
