Église de la Madeleine de Troyes is a Gothic style church built in the 13th century. It was restored in the 16th and 17th centuries. The Renaissance-style square tower dates from 1525, as does the richly sculpted gateway to the former cemetery.
Sainte-Madeleine is remarkable for its famous rood screen and the stained glass windows in its chevet, masterpieces of exceptional finesse that visitors can admire at a glance.
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.
