The Alatskivi Manor (Allatskiwwi in German) was first mentioned in 1601. In 1628 Swedish king Gustav Adolf II donated it as a gift to his secretary Johan Adler Salviusele. In 1642 the manor was further passed into the possession of Hans Dettermann Cronmann and in 1753 it was bought by Otto Heinrich von Stackelberg.
The present huge castle manor was designed by the land owner Arved von Nolcken. He had travelled in Scotland and fascinated to the Balmoral Castle. Von Nolcken wanted to build a copy of royal castle to Alatskivi. The new neo-Gothic main building was completed in 1885 and it was one of the most luxurious manor houses in Estonia.
At present, the building is owned by Alatskivi Community and being restored to serve as a museum and restaurant.

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.
