The chapel of Lemböte is a ruined stone church in Lemland. It has dated to the beginning of 16th century, but first records of the chapel are from the 13th century. Lemland was then an important waypoint between Denmark and Baltic.
Archaeologists found a treasure of 270 silver coins inside the chapel in the 19th century. Coins are today in the Åland museum.
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.
