Gomirje is the westernmost Serb Orthodox monastery in Croatia. It was built in the period of the first larger Serb settling in the villages of Gomirje, Vrbovsko and Moravice at the end of 16th and the beginning of the 17th century. The monastery is thought to have been founded in 1600. The monastery includes the church of Roždenije saint John the Baptist, built in 1719. In 1789, the monastery was devastated by fires and subsequently rebuilt in 1791.
During World War I, Austria-Hungary turned Gomirje Monastery into concentration camp for Serbian Orthodox priests from the Triune Kingdom and areas of Vojvodina. During the World War II, the Ustaše government of the Independent State of Croatia killed monastery monks and took all of the monastery's valuable possessions to Zagreb, while the complex itself was burned in 1943. The monastery was reopened in 1967.
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.
