Bydlin Castle was built in the 14th century and appears in documents after 1389. The builder of the castle was probably Niemierza of Strzała or his father Pełka. At the end of the 15th century the stronghold became the Brzezickis’ property, and then the Szczepanoskis’ and the Boners’. In the second half of the 16th century Jan Firlej transformed the castle into the Arian Protestant Church, and at the end of the 16th cent. his son, Mikołaj Firlej, converted it into the Catholic Church of the Holy Cross. The building was abandoned at the end of the 18th century due to escalating assaults of the brigands and since then it has been falling into ruin.
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.
