Somló castle was built in the 13th century soon after the Mongol Invasion. It had a great deal of owners. Kinizsi Pal was also among them but the castle’s golden age was when the bishop of Eger, Bakócz Tamás bought it in the late 15th century. He rebuilt it and it served as a castle and as a chapel. The Turkish tried to occupy several times unsuccessful. By the 18th Century it was a bad condition. The ruins are not easy to reach, but when you get there, you will have a spectacular view on the Somló wine region.
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.
