Uuemõisa estate (Neunenhof) is first mentioned in 1539 and then belonged to the Bishopric of Saare-Lääne. During the Swedish time it for a long period of time was a part of the vast domains of the De la Gardie family. The last owner before the Estonian land reform of 1919 was Eugenie Mikhailovna Shakhovskaya, the world's first female fighter pilot. After the Estonian declaration of independence, it was used by the Estonian Ministry of Defence. During the Soviet occupation of Estonia, the Red Army occupied the buildings. The current manor was built in mid 19th-century, with additions made in 1921-1923 by architect Karl Burman.
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.
