Leienfels Castle was a late medieval aristocratic castle, immediately northwest of the eponymous village of Leienfels in the region of Franconian Switzerland in Germany.
The ruins of the hill castle are freely accessible and act as a viewing point. The castle may be reached from the village of Leienfels by heading in a northwesterly direction. The site of the castle begins at the edge of the village.
In the vicinity, towards the west, lie the ruins of Bärnfels Castle, to the north, on the Bleistein near Graisch, is the site of Leuenstein Castle. To the southeast is the site of Leupoldstein Castle and, to the southwest, in the valley of the Trubach, were other castles, of which ruins or foundations (Burgställe) still exist.
The castle, whose name is probably derived from Löwenfels ('Lion Rock'), is one of the later castles to be built in Franconian Switzerland and may have been erected in the 14th century at the behest of Seibot I of Egloffstein, who is recorded between 1285 and 1332.
The castle itself is first mentioned in 1372. Lord Götz of Egloffstein had to give his part of the hitherto probably allodial castle to the Bishop of Bamberg after a feud.
In 1380 the castle was captured by troops of the Bishop of Bamberg and Burgrave Frederick V of Nuremberg. Götz of Egloffstein was taken prisoner and incarcerated in Nuremberg. His successor was also frequently involved in feuds. The castle was destroyed in 1397 on the orders of Emperor Wenceslaus.
In the Peasants' War the castle was badly damaged in 1525, but its garrison under Otto of Mengersdorf was able to prevent it being taken. The restoration of the castle was carried out immediately. In 1553, during the Second Margrave War, it was again seriously damaged. Its reconstruction was carried out more slowly this time. In 1594, Leienfels was incorporated into the episcopal Amt of Pottenstein. By 1610, the site was already being described as uninhabitable. In 1643, during the Thirty Years' War the repair of the castle was no longer considered to be worthwhile. In 1646, the bricks were of the surviving buildings were carried off and the site left to decay.
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.
