The Church of St. Chrysogonus isnamed after Saint Chrysogonus, the patron saint of the Zadar.
The Romanesque church was consecrated by Lampridius, Archbishop of Zadar, in 1175. Built at the site of a Roman emporium, it replaced the Church of Saint Anthony the Hermit and is the only remaining part of a large medieval Benedictine abbey. In 1387, Elizabeth of Bosnia, the murdered queen dowager of Hungary and Dalmatia, was secretly buried in the church, where her body remained for three years until being moved to the Székesfehérvár Basilica. The construction of a bell tower began in 1485, but was abandoned in 1546 and never finished.
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.
