Church of Our Lady Assumed into Heaven in Ostrzeszów is a late-gothic parish church, founded by King Casimir the Great in mid-14th century. It was initially composed of presbytery and a sacristry. The nave was added in 1360. After the destruction by a fire of the late 15th century and by the Swedish invasion in mid-17th century, the church was rebuilt in 1721–1723. Gothic-style stained-glass windows were fixed in 1939.
The church’s altars are baroque in style – the main one containing a copy of The Assumption of Our Lady by the famous Spanish painter Murillo. The chancel arch features limewood sculptures, probably made by Albrecht Dürer.
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.
