The history of the Haikko manor dates back to 1362 when a Dominican monastery owned the site. Jöns Olafsson Stenbock bought the manor and Haikko was a residence of Stenbock family for next 400 years. In 1871 it was bought by general Sebastian von Etter. Several members of the Russian Imperial family visited Haikko because von Etter was a close friend to czar Nicholas II. During the revolution in 1917 Grand Duke Kiril´s eldest son Wladimir was born and christened at Haikko. He was the nearest aspirant to the imperial crown of Russia and he became later the head of the Romanov family.
Current main building was built in 1913. The Vuoristo family purchased the manor in 1965. Today Haikko provides conference center, spa and hotel facilities.
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.
