The royal castle of Jungshoved was mentioned in 1231. The annexed church dates from the same period. The castle is thought to have been built as early as in the 1100s as part of King Valdemar I's coastal defences against the Wends (Baltic Slavs). The castle is strategically located at the mouth of Skibbinge Cove. Jungshoved may also have been implicated in the monarch's control of the herring market at Falsterbo. After the Dano-Swedish wars of the 1600s, the castle was in ruins. The last structures were removed in the 1700s and the building materials reused for barracks and stables for Prins Jørgen's Palæ, a three-winged hunting seat in Vordingborg.
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.
