St. Florin' s Church is a triple-naved Romanesque pillared basilica (founded in the 12th century) with Gothic chancel (1350) on Roman tower. The original flat timber ceiling was renewed in 1708, and the squat towers were replaced in 1900 by pointed ones. Nearby is the city's oldest dwelling house.
Opposite, where the vicarage belonging to the Church of our Beloved Lady now stands, is the site where the central section of the Franconian royal court originally stood in the 6th century.
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.
