Lysá nad Labem was firstly mentioned in the Chronica Boemorum, with its existence mentioned in 1034. In the 13th century, a castle was built here and until the reign of the Luxembourgs, the town was property of the Czech queens. Since 1291, there has been evidence of Lysá being a town. In that year, Queen Judith of Habsburg issued a charter to unite the settlements of the Lysá estate into one economic unit.
During the Hussite Wars the town suffered a lot. At the turn of the 15th and 16th century, the Smiřický family of Smiřice rebuilt the dilapidated castle into a late-Gothic castle. In 1548, Emperor Ferdinand I added Lysá to the intimate dominion as a hunting centre. After a large fire, he had the castle rebuilt in the Renaissance style.
The sustainable development of the town was stopped by the Thirty Years' War. In 1647, Lysá was acquired by the empire general Johann von Sporck and then the town began to flourish. After the general's death, his son Franz Anton von Sporck began to reign. He made the most important changes in 1696 when the Augustinian monastery was restored and the new parish church and the Chapel of Three Kings were built.
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.
