The Visovac Monastery was established in the 14th century by Augustinian monks, who erected a small monastery and church on the island dedicated to the Apostle Paul. In 1445, it was enlarged and adapted by Franciscans, who settled on the island having withdrawn from parts of Bosnia when invading Turks had taken over. A new monastery was constructed in the 18th century.
The oldest preserved part of the current complex dates from the 14th century. The monastery houses a historically significant collection of Christian books and a rich library containing many historical manuscripts and rare books, including a rare incunabula of Aesop's fables (Brescia 1487) printed by the Lastovo printer Dobrić Dobričević, and a collection of documents known as 'the sultan's edicts'. A sabre once belonging to Vuk Mandušić, one of the best-loved heroes of Serbian epic poetry, is also housed at Visovac.
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.
