Built in 333 BC along Gela's western coastline at Capo Soprano by the tyrant of Syracuse, Timoleon, Gela's ancient Greek fortifications are remarkably well preserved, most likely the result of being covered by sand dunes for thousands of years before their discovery in 1948. The 8m-high walls were originally built to prevent huge amounts of sand being blown into the city by the blustery sea wind. Today authorities have planted trees to act as a buffer against the encroaching sand.
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.
