Almnäs Castle was built in 1773-1776 by the General Wolter Reinhold Stackelberg. It is situated at a cove of a lake and is surrounded by notable park. Later the property belonged to the families Sparre, Bielke, Horn, Ehrensten and others. It was purchased in 1859 by Gustaf Sparre, first speaker at the Swedish Parliament, and in 1898 by Baroness Marika Dickson from Gothenburg. Almnäs is not open to the public.
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.
