Archangel Michael's Church was built in the 12th century for the newcomers who were settling down in the neighbourhood of Znojmo Castle. The consecration to Archangel Michael and the location on the highest point of Znojmo seem to imply that this church might have replaced an ancient pagan occult place. However, the medieval history of the church does not seem to be free from dramatic events: in the early-15th century the Hussites bombed the church so it had to be built anew. In the 16th century Lutheran preachers got hold of it, when the church tower collapsed for the first time (1581). In 1624 the Jesuits took over the ravaged place and rebuilt it. In 1642 the church tower collapsed for the second time, not to be built again as part of the church structure. In 1852 they built a new tower separately from the church.

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.
