The Monastery of St. Stephen was founded by St. Antoninus Cantacuzene, who is thought to be a son of the Serb ruler Nicephorus II of Epirus, in c. 1400.
This monastery rests on the plain rather than on a cliff. It was shelled by the Nazis during World War II who believed it was harboring insurgents and was abandoned. The monastery was given over to nuns in 1961 and they have reconstructed it into a flourishing nunnery, with 28 nuns in residence in 2015.
The old katholikon (main church), which was rebuilt in 1545 and frescoed shortly thereafter, still stands. The new katholikon was built in 1798 and is currently being frescoed by a modern artist. It is dedicated to the martyred St. Charalambos, whose head it contains.
The refectory (15th century) has a surviving fresco of the Virgin in the apse. The monastery contains a small museum of vestments and other religious objects and the nuns sell handmade embroideries and other trinkets.
Monasteries of Meteora are included on the UNESCO World Heritage List.
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.
