In the 13th century, the Lords of Wiltz built a fortified castle on a rocky promontory, initiating the development of the upper town of Wiltz. In 1388, the French attacked the town and burnt the castle down but it was soon repaired. In 1453, Wiltz was again attacked, this time by the troops of Philip of Burgundy. The round Witches' Tower to the east of the gardens is the oldest part of today's castle. Under Count John VI of Wiltz, the construction of today's Renaissiance style castle was begun in 1631. After delays caused by the Thirty Years War, the main building was not completed until about 1720. The old chapel was finished in 1722 and the monumental staircase leading down to the gardens was completed in 1727. The castle premises were acquired by the State of Luxembourg in 1951 for use as an old people's home.
Since 1953, Wiltz Castle has been the venue of an international music festival attracting artists and orchestras of international repute. Since 1999, the castle's stables have housed the National Museum of Brewing. The museum traces the history of beer production over the past 6,000 years, especially more recent developments in Luxembourg. The little tanning museum (Musée de la Tannerie) presents the history of the leather industry in Wiltz which dates from 1644.
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.
