Červený Kláštor (Red Monastery) was founded in the early 14th century, during the Hungarian Kingdom. Court documents from 1307 state that a man by the name of master Kokoš from Brezovica, founded six monasteries as a punishment for murder. In 1319 he donated 62 sectors of his village, Lechnice to the Carthusian order. A wooden structure was built in 1330, which was later replaced by bricks and stones. The monastery gets the name 'Red' from the red tiles that were used on the roofs.
The monastery suffered several quarrels with Czorsztyn lords, and was occupied by Hussites in 1431 and in 1433. It was adversely hit by the Battle of Mohács in 1515, and in 1545 Czorsztyn Knights from Niedzica Castle attacked the monastery, and the monks fled across the Dunajec River into Poland. The monastery was abolished during the Reformation in 1563, becoming a private residence for wealthy noblemen.
In 1699, Ladislav Maťašovský, a bishop in Nitra, purchased the monastery, and donated to the Camaldolese order, who settled down it this area in 1711. In 1782 it was secularized as part of Emperor Joseph II's campaign against monastic orders that in his view didn't pursue useful activities. The monastery’s library was sold to Budapest, and the church equipment to Muszyna, Poland.
In 1820 the Emperor Franz Joseph I donated the monastery to the newly founded Greek-Catholic diocese of Prešov.
The monastery suffered a fire in 1907 and was heavily damaged during the Second World War, but after being rebuilt in 1956–66 it was opened again and serves as a museum.
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.
