Košljun is a tiny island in Puntarska Draga bay off the coast of Krk, facing Punat. It is approximately 300 meters in diameter and covers an area of 6.5 hectares, but is rich in vegetation. The only inhabitants are a group of Franciscan friars living in St. Mary's Monastery.
The earliest known settlement on Košljun was a Roman villa rustica belonging to a landowner of the Roman settlement on Krk. The next solid evidence of inhabitation is a written record from 1186 implying the existence of a Benedictine abbey built on its foundations. This was abandoned in 1447, and the Frankopans moved in Franciscans in their place. The present church was built by the Franciscans in 1480. The Benedictines remained on the island until the 15th century. After the death of the abbot Dominik, a Venetian priest held the title of Abbot of Košljun, and the island was abandoned.
A pair of Franciscan friars complained to the Pope that the monastery was sitting empty. At their request, the Benedictine monastery was abolished and the island of Košljun given to the Franciscans, whose monastery remains today.
By the jetty there is a statue of St. Francis with a wolf, a frequent iconographic motif for this saint. As well as the statue there is also a text written in Glagolitic over the main entrance to the monastery, 'Mir i Dobro' (peace and well-being) which is also dedicated to St. Francis. In the monastery there is an ethnographic collection including articles used by farmers and fishermen on Krk from the end of the 19th and the beginning of the 20th century.
There is also a permanent exhibition of church artefacts housed in the old Benedictine church from the 12th century. As well as old masters the collection also includes works by more recent Croatian artists and sculptors such as: Dulčić, Bulić, Radauš, Orlić and Kršinić. The monastery also owns a rich library of some 15,000 books which contains a Jewish Bible from the 11th century, Glagolitic sermons and Ptolemy's Atlas, printed in Venice in 1511.
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.
