Alikartano (Frugård) manor was established in 1608 and it was owned by the famous Nordenskiöld family from 1709 to 1912. The current main building was built in 1805 and it represents various architecture styles including baroque, neoclassical and rococo.
Today Alikartano is a museum exhibiting scientific achievements of the Nordenskiöld family. Some rooms are decorated in the 19th century style. The museum is open in summertime from Wednesday to Sunday.
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.
