Just in front of Vlaherna Monastery there is an island called Pontikonissi on which there is only one building: the church of Pantocrator. According to one interpretation of the Odyssey this island would be the ship of Ulysses that was turned into rock by Poseidon while, according to another legend would be the rock on which Ulysses' ship crashed during a storm.
The church of Pantocrator was built in the 13th century and to visit it you can take a boat from the small port opposite. The Byzantine chapel that is on the top of the island encloses the memorial tablets of Elizabeth Empress of Austria and Rodolfo archduke.
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.
