The church Santa Maria Maggiore (late 15th century) stands on the site of the former Lombard church of San Martino (founded in the second half of the 8th century). It has a rectangular shape with a polygonal apse and is oriented east-west. It has a single nave, divided by three arches. It is decorated with early 15th-century frescoes. The frescoes at the bottom of the north wall even belong to an earlier period. The contemporary wooden statue of the Madonna Enthroned is also of special interest.
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.
