Agarathos is one of the oldest monasteries in Crete but its exact date of establishment is not known. Most probably, it was established during the second Byzantine period and originally belonged to the Kallergis family. According to tradition, it received its name from a Jerusalem sage bush (agarathia in the Cretan dialect), under which an old icon of Virgin Mary was found.
The earliest written reference to the monastery dates back to 1532 and the Venetian period. During that time, Agarathos was a very wealthy monastery, with many of its monks originating from Kythira. During the Ottoman occupation of Crete, the monastery often served as a local revolutionary center and suffered several retaliatory attacks as a result. Several important figures, among which Cyril Lucaris, Meletius Pegas, Joseph Bryennios, Gerasimos Palaiokapas and Theodore of Alexandria, have been enrolled as monks at Agarathos.
Agarathos monastery is built with a fortified architecture. The main building (katholikon) is a two-nave church that was erected on the location of an older one and was inaugurated in 1894. One nave is dedicated to Kimisis and the other to St. Minas. In 1935, the church was declared as a preservable monument. An old church dedicated to St. Raphael is located outside the courtyard.
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.
