The first written record of the Blankenfelde manor dates from 1689 when the owner was Ernst von Medem. The estate changed owners several times and was part of the von Hahnide family from 1840 until 1920. Between 1804 and 1805 the manor belonged to the Russian imperial house of Andreas von Königfelsile. Louis XVIII, King of France, lived in Blankenfelde manor for a while when he was in exile.
The complex structure of the manor dates from the mid 18th century, and the main building erected in 1743 has a 19th-century English-style park. There are currently ideas for the exploration of the estate in the concept of private ownership and tourism. The renovation work of the main building is now underway. Blankenfelde estate flower garden is part of the spring tulbifestivale.
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.
