The church of St. Christoph in Mainz, known in German as St. Christoph zu Mainz, is an example of early gothic architecture. St. Christoph was originally built between 1240 and 1330. In the 17th and 18th century, the church was renovated and redesigned in Baroque architecture. The church is associated with Johannes Gutenberg, who may have been baptised there.
During World War II it was razed except for the external walls. During the great air raid on Mainz on 12 and 13 August 1942 St. Christopher burned down, whereas a renewed bombing on 27 February 1945 with tactical demolition bombs brought the vaults to collapse. The outer walls have been restored and protected on the north side by concrete columns. The new buttresses have been provided with a relief by the Mainz sculptor Heinz Hemrich carrying symbolic representations of the city's history. Today ruins represent the central war memorial in the city of Mainz, in memory of the victims and the destruction of the city in World War II, such as the bombing of Mainz on 27 February 1945.
Right next to the church stands the most modern Gutenberg statue of the city. It was created to celebrate the year 2000 Gutenberg celebrations of Mainz by sculptor Karl Heinz Oswald. The iron sculpture displays the Gutenberg printing press. Gutenberg used for printing a wooden press, reminiscent of construction, mechanics and operation of a wine press. The windows in the chancel and the glass wall in the chancel were designed by Alois Plum.
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.
