There has been a manor house on the site of Keila-Joa manor (Schloss Fall) since the 17th century. The present manor house was built in 1831-1833 and designed by St. Petersburg architect Andrei Stackenschneider. The manor represents one of the earliest examples of neo-Gothic architecture in Estonia. It was built for the family of count Alexander von Benckendorff (whose graves can be found in the park adjacent to the manor) and the building saw many prominent guests during the Imperial years, among others the Russian royal family, famous soprano Henriette Sontag and composer Alexei Lvov.
From 1927 to 1940 it was used by the Estonian Ministry of Foreign Affairs. During the Soviet occupation it was used by the Red Army. The centre of the manor now belongs to the Estonian Ministry of Foreign Affairs, but is not being used currently and is awaiting restoration. In 2010 the manor was sold into private hands.
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.
