The history of Leineperi (Fredriksfors in Swedish) village dates back to the 1630s. The ironworks was founded in 1771 by Berndt Johan Hastfehr. Until the end of 19th century ironworks manufactured all kinds of iron tools like nails, bolts and spades. The ironworks expanded little by little and in the the 19th century Leineperi was one of the largest iron manufacturers in Finland. The ironworks area consisted several manufacturing plants and residences of workers.
The ironworks business ended in 1902 and the site was moved as farm. Today Leineperi Ironworks presents a living example of the first stages of the industrialisation in Finland. A blast furnace and a bar-iron forge are some of the attractions at the site. The smiths' old cottages serve as workshops of the craftspeople and artists. The ironworks village offers also various events in historic industrial mileu, such as Spring, Autumn and Christmas Markets, Antique Fairs, Metal Art Weeks, summer theatre, wedding banquets, meetings etc.

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.
