Arsaniou Monastery for old men was possibly founded during the 2nd Byzantine period (961-1204). It was founded by a monk named Arsenios, after whom it was named.
According to the most likely version of events, it was deserted at one point due to pirates causing problems to coastal hamlets and, like many other Cretan monasteries, it was renovated before 1600. The Church of Agios Georgios, the Catholicon of the Monastery, a cruciform domed basilica, was inaugurated during the late 16th century.
The great earthquake of 1856 destroyed a large part of the monastery and a decade later, the monks donated its property for the war of liberation of 1866. During the final Cretan revolution (1897-1898), Arsani suffered its own holocaust, with the Abbot Gabriel Klados meeting his doom after conflict with the Ottomans. This was the final contribution of the monastery shortly before the liberation of Crete.
The next landmark in the history of the monastery came in 1941, when the Germans executed monk Damianos Kallergis for fostering guerillas.
The monastery was renovated in the early 1970s, with the addition of murals to the church and the construction of the museum and conference center.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
