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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
