According to various historical sources, Vosakou monastery was in continuous use from the early 17th century until 1960, when the last of its monks died. In April 1676, Vossakos became a Patriarchical monastery (i.e. stauropegic), proclaimed by an act of Ecumenical Patriarch Parthenius IV. The monastery played an important role in the greater area of Mylopotamos and owned many pieces of land as well as establishments in the nearby villages of Sisses, Garazo and Dafnedes. It also contributed to the Greek Revolution of Independence in 1821 and the Cretan Revolution of 1866. This involvement resulted in the monastery being partially destroyed by the Turks. Later in the 19th century, the monastery was rebuilt through significant construction activities. The current main church (katholikon) was built in 1855, replacing an earlier one dating from the 14th and 15th centuries.
The monastic complex is arranged in three wings around the main church which is situated on the east side of the central yard. It is a single-aisled, vaulted church that is characterized by simple artistic features. A fountain built in 1673 is located near the main church. The monastery's water supply system is complemented by two water-cisterns, collecting the water draining from the roofs with a system of pipes. The east wing of the monastery is determined by its monumental gate of 1669 and two small rooms. The south and west wings comprise the dining hall, kitchen, honey and wax workshops and the raki distillery. An open-air wine-press is located in the central wing.
After being abandoned for over 40 years, the monastery was reinstated in 1998. An extensive restoration project was undertaken by the 28th Ephorate of Byzantine Antiquities, funded by the municipality of Kouloukonas, the Region of Crete and the monastery itself. Today, about two thirds of the originally derelict buildings have been restored and works are still under way.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
