Accordin the legend St. Martin was once imprisoned in a dungeon underneath this church in Worms, which was built in the 12th century. It was the chapter church of the Martinsstift, which no longer survives. Until the 15th century, the Martinskirche was a burial place for the Kämmerer family, named von Dahlberg, whose courts lay nearby in the Kämmererstrasse.
The church is a Romanesque church, with red sandstone walls whose whitewash was recently stripped away. It is a buttress basilica with three naves and a straight chancel. Architectural forms from the 12th century.
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.
