Kamarina was an ancient city on the southern coast of Sicily. It was founded by Syracuse in 599 BC, but destroyed in 552 BC.
The Geloans, however, founded it anew in 461 BC, under the Olympic charioteer Psaumis of Camarina. It seems to have been in general hostile to Syracuse, but, though an ally of Athens in 427 BC, it gave some slight help to Syracuse in 415–413 BC. It was destroyed by the Carthaginians in 405 BC, restored by Timoleon in 339 BC after its abandonment by Dionysius' order, but in 258 BC fell into the hands of the Romans.
Its complete destruction dates from AD 853. The site of the ancient city is among rapidly shifting sandhills, and the lack of stone in the neighborhood has led to its buildings being used as a quarry even by the inhabitants of Gela, so that nothing is now visible above ground but a small part of the wall of the temple of Athena and a few foundations of houses; portions of the city wall have been traced by excavation, and the necropolis has been carefully explored.
Just before the Carthaginians razed Kamarina in the 5th century BC, the Kamarinians were plagued with a mysterious disease. The marsh of Kamarina had protected the city from its hostile neighbors to the north. It was suspected that the marsh was the source of the strange illness and the idea of draining the marsh to end the epidemic became popular (the germ theory of disease was millennia in the future, but some people associated swamps with disease). The town oracle was consulted. The oracle advised the leaders not to drain the marsh, suggesting the plague would pass with time. But the discontent was widespread and the leaders opted to drain the marsh against the oracle's advice. Once it was dry, there was nothing stopping the Carthaginian army from advancing. They marched across the newly drained marsh and razed the city, killing every last inhabitant.
The story of the marsh is told by the Roman geographer Strabo and repeated by Carl Sagan in Pale Blue Dot. The story of the city is recounted by the latter author as a lesson: that action guided by fear and ignorance often intensifies the problems it seeks to ameliorate.
Modern remains are scanty. They include archaic tombs (seventh century BC) and ruins of a temple of Athena. Nearby are tombs of a necropolis from the fifth-fourth century BC. Part of the remains are now in the archaeological museum of Syracuse. The archaeological park includes the remains of a 'Hamman qbel Jamaa' - public baths used before entering the mosque, one of only two known on the island.
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.
