St. Francis Xavier Cathedral is a Roman Catholic cathedral in Hrodna (Grodno). The construction of the church started in 1687. The completed building was consecrated in 1705 to St. Francis Xavier. The monastery was dissolved in 1773 and the church became a parish one. In 1990 it was granted the title of Minor basilica. Originally a Jesuit church, it became a cathedral in 1991, when the new diocese of Grodno was erected.
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.
