The Magnuskirche is a small church in Worms, to the south of Worms Cathedral. It is the city's smallest church. Archaeological evidence and its dedication (probably identifiable with Magnus of Füssen, a Carolingian saint) suggest it originated in the 8th century - part of that building survives in the nave's north wall.
The first written record dates to 1141. It was enlarged many times between the 10th and 15th centuries and during that era served as the nearby Andreasstift's parish church. It is the oldest Lutheran church in south-west Germany, since Martin Luther stayed in it and preached in it during the 1520 Diet of Worms. After the severe damage to the city in 1689 during the Nine Years' War, the church was restored in the Baroque style in 1756. It was destroyed by Allied bombing on 21 February 1945 and restored again in 1953.
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.
