At the beginning of the Kalmar Union age Sandemar was owned by the Teutonic Order of Livonia. Erik Axelsson Tott bought all the Order's property in Sweden in 1467. During the 1500s the ownership was unknown. In the 1600s the Sandemar belonged to families Oxenstierna, Bonde and Falkenberg. The Royal Council and president Gabriel Falkenberg completed the present main building around the year 1693. Sandemar is today privately owned by Karin Mattson Nordin, daughter of the real estate developer John Mattson.
The main building of Sandemar is made of wood, covered with tiles and the water side plates to protect against sea winds. The farm escaped the Russian ravages in 1719, probably through the deterrent effect of the nearby Dalarö Fortress had, and have therefore preserved the Carolinian period decorations. The English garden is added later with greenhouse, vegetable and fruit tree plantations.
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.
