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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
