The Zavala Monastery is a Serbian Orthodox monastery located in the village of Zavala on the southwestern edge of Popovo Polje, in Ravno. The monastery is dedicated to the Presentation of Mary. The northern wall of the monastery's church is situated within a cave. This monastery is also known as a place where Basil of Ostrog entered into monasticism.
Along with Žitomislić and Tvrdoš, Zavala is one of the most important monasteries in East Herzegovina. The first written record of the monastery dates back to sixteenth century. During the Second World War, the monastery suffered major damage, and in the Bosnian War it was further damaged and abandoned.
After the war the monastery was restored, and together with Zavala village with its old architecture and stone masonry, and Vjetrenica cave constitute cultural-historic, architectural and natural assemble, protected by KONS as an important national monument of Bosnia and Herzegovina. Because of its importance as national heritage, as well as tourist and ambiental attraction, site is also placed on the UNESCO Tentative list for inscription into UNESCO World Heritage Site list.
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.
