Palike was an ancient city on Sicily. Its archeological site is located in Rocchicella on a spur of basalt in the valley of the Margi river. There are no certain origins to this ancient town. Diodorus Siculus writes that it was founded in 453 BCE by the native Sikel leader Ducetius. It was named after the sanctuary of the Palici nearby. The city was surrounded by strong walls and grew rapidly because of the fertility of its soil. However, it was soon destroyed and the site remained uninhabited at the time Diodorus wrote the Bibliotheca historica, which he finished in approximately 60 BCE.
Palike's destruction most likely happened in 440 BCE, when the city of Trinakie was destroyed by Syracuse according to Diodorus Siculus. Ducetius had died of an illness earlier in the same year. Peter Green and several other historians argue that Trinakie was most likely the same city as Palike. The table of contents of the Bibliotheca historica refers to the Syracusan campaign as being conducted 'against the Picenians', which makes no sense. If the spelling of the Ancient Greek text is slightly altered, this would read 'against the men of Palici'. Trinakie is an ancient indigenous name for Sicily, which would have been a suitable name for the nationalistic ambitions of the Sicels. The city might have been renamed to Trinakie or it could have been the name of its acropolis.
References: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.
