The Basilica of St. James and St. Agnes is a basilica minor in Nysa. It is the largest sacramental building in the town, and historically cultural site of the town. The basilica was built on the turning point of the twelfth and thirteenth centuries, in the area known as the New Town. It was the first parish church, raised in between 1195 and 1198, consecrated by Wrocław's Jarosław Bishop in 1198.
The current church was built in two phases. The first stage was built before 1392, when the six-span church was built. The second stage was built between 1424 and 1430, when the chancel and ambulatory were built. St. James's Church was the highest building in the town at that time, with its rooftop surpassing all of the town's structures; taking part in an exceptionally historic part of town.
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.
