The Karakalou Monastery is situated on the southeast side of the Athos Peninsula in northern Greece, between the monasteries of Great Lavra and Iviron. Karakalou is dedicated to the Apostles Paul and Peter. It is ranked eleventh in the hierarchical order of the twenty monasteries located on the Mount Athos peninsula.
Founded in the 11th century, the monastery received its name after either the Roman emperor Karakala or the monk, Karakalas, who was said to be its founder. Karakalou was first mentioned in documents from 1018 and 1087. Built on the side of a mountain Karakalou appears now like a fortress overlooking the Mediterranean Sea, the consequence of having been destroyed twice.
In the 14th century it was devastated by Latin and pirate raids during the period of occupation by Frankish forces after they had conquered Constantinople in 1204. Then, prior to its rebuilding in the 16th century, the monastery was destroyed again by pirates. The emperors Andronic II and John V Paleologos rebuilt Karakalou after the first destruction and after the second raid it was rebuilt by Peter, the ruler of Moldavia and his descendants. According to the local athonite tradition, later on, Peter took monastic vows at Karakalou. In the 17th century, Karakalou was given ownership of the dependency of St. Nicholas in Ismaelia. Under Ottoman rule the monastery lost its estates to expropriation by the Turks. The monastery also played a role in the struggle by the Greeks for liberation of their homeland from Ottoman rule.
The main church, the katholikon, was built between 1548 and 1563 in the Athonite style. The murals were added in 1716, and in 1763 the outer narthex was painted with scenes from the Book of Revelations. The church houses a portable icon of the Apostles that was painted by Dionysius in the early 18th century. There are seven chapels within the walls of the monastery. In addition the monastery has eighteen Kellia, four in Karyes and fourteen in the forest southwest of the monastery. The monks of Karakalou have followed the coenobium discipline since 1813.
In its treasury, Karakalou, among many vestments, ecclesiastical vessels, and relics of saints, possesses portable icons of Ss. Peter and Paul and the Circumcision of Christ, and a piece of the Holy Cross. The library contains 279 manuscripts, including 42 on parchment, some 2,500 printed books, and many official documents.
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.
