Hippana was an ancient town of Sicily, mentioned by Polybius as being taken by assault by the Romans in the First Punic War, 260 BCE. Diodorus, in relating the events of the same campaign, mentions the capture of a town called 'Sittana', for which we should in all probability read 'Hippana'. It sat astride the main road from Panormus (modern Palermo) to Agrigentum (modern Agrigento) upon Monte dei Cavalli.
Some manuscripts of Pliny mention the name of Ipanenses in his list of Sicilian towns, where the older editions have Ichanenses. If this reading be adopted, it in all probability refers to the same place as the Hippana of Polybius; but as the reading Ichanenses is also supported by the authority of Stephanus (who notices Ichana as a town of Sicily), the point must be considered doubtful.
References:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
