The Church of All Saints, also known as Holy Cross Church (Kreuzkirche) was built in 1478 by Jörg von Halsbach and was the first church with a cemetery in the St. Peter parish. It was once located at the crossing of four roads, whence the original suffix am Kreuz ('at the Cross').
It has unadorned brickwork walls, Gothicvaults and a tall bell tower. The interior was rebuilt from 1620 in Baroque style, the only remaining Gothic elements being the nave's vault, fragments of a fresco and a Crucifix by Hans Leinberger. The tomb of banker Gietz and the Apparition of the Virgin to St. Augustine (by Hans Rottenhammer) are in Mannerist style.
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.
