St. Sebaldus Church is one of the most important and oldest churches of Nuremberg. It takes its name from Sebaldus, an 8th-century hermit and missionary and patron saint of Nuremberg. It has been a Lutheran parish church since the Reformation.
The construction of the building began in 1225. the church achieved parish church status in 1255 and was completed by 1273-75. It was originally built as a Romanesque basilica with two choirs. During the 14th century several important changes to the construction were made: first the side aisles were widened and the steeples made higher (1309–1345), then the late gothic hall chancel was built (1358–1379). The two towers were added in the 15th century. In the middle 17th century galleries were added and the interior was remodelled in the Baroque fashion. The church suffered serious damage during World War II and was subsequently restored. Some of the old interior undamaged includes the Shrine of St. Sebaldus, works by Veit Stoss and the stained glass windows.
The church had an organ by the 14th century, and another by the 15th. The main organ had been built in 1440–41 by Heinrich Traxdorf, who also built two small organs for Nuremberg's Frauenkirche. Until its destruction in the 20th century it was one of the oldest playable organs in the world. The Traxdorf organ was rebuilt in 1691. The modified case was destroyed by the Allied forces during a bombing raid on 2 January 1945.
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.
