Innsbruck Cathedral was built between 1717 and 1724 on the site of a 12th-century Romanesque church. The interior is enclosed by three domed vaults spanning the nave, and a dome with lantern above the chancel. With its lavish Baroque interior, executed in part by the Asam brothers, St. James is considered among the most important Baroque buildings in the Tyrol.
Innsbruck Cathedral is notable for two important treasures. The painting Maria Hilf (Mary of Succor) by Lucas Cranach the Elder from c. 1530 is displayed above the main altar. It is considered among the most venerated Marian images in Christendom. The cathedral also contains in the north aisle the canopied tomb of Archduke Maximilian III of Austria, Grand Master of the Teutonic Knights, dating from 1620. The cathedral was heavily damaged during World War II, but was fully restored within a few years.
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.
