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.
Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
