Kuitia is the oldest remaining manor house in Finland. It was built of stone probably in 1480s by noble Joachim Fleming. There has been a manor house in same location from the beginning of the 15th century. Earliest known owner of Kuitia was Maunu Tawast, a bishop of Turku, who donated manor to his brother in 1439.
Because Danish soldiers plundered coastal villages in the 15th century, Kuitia was built also for defensive purposes. Originally the present stone house was part of a foursquare, inner court structure. Current wooden residence was built in 18th and 19th centuries. Kuitia has been privately owned by af Heurlin family about 150 years and is still in living use. Kuitia is open for visitors only with group excursions.
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.
