Sövdeborg area belonged to bishops of Lund in the Middle Ages, but after Reformation the Crown of Denmark sold it to Frederik Lange in 1587. He built the new castle to the southern side of small Sövdesjön lake between 1590-1597. It consisted of a moat, tower and central section with two wings. Count Erik Piper made an major reconstruction to the castle in 1840-1844.
Sövdeborg is open to the public. The most impressive room is the stone hall in the southeast corner of the ground floor, with its unique ceiling of stucco and oak. To the west of the house, part of the partially drained lake has been transformed into an English park, with waterways. Water is led into these channels and the old mansion house channels from the lake to the north.
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.
