St. James's church (often mistakenly called St Jacob's), a basilica from the 14th century, with monumental wall paintings and Gothic stalls. The unique character of the church is determined by a myriad of decorations, detail styles and multicolour glazed brick. In the New Market Square, the church can be entered through the Gothic gate with a pillar and the Baroque figure of St. James, the patron.
References: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.
