The Pnyx is a hill in central Athens. Beginning as early as 507 BC, the Athenians gathered on the Pnyx to host their popular assemblies, thus making the hill one of the earliest and most important sites in the creation of democracy.
Pnyx is a small, rocky hill surrounded by parkland, with a large flat platform of eroded stone set into its side, and by steps carved on its slope. It was the meeting place of one of the world's earliest known democratic legislatures, the Athenian ekklesia (assembly), and the flat stone platform was the bema, the 'stepping stone' or speakers' platform. As such, the Pnyx is the material embodiment of the principle of isēgoría, 'equal speech', i.e. the equal right of every citizen to debate matters of policy.
Today the site of the Pnyx is under the control of the Ephorate of Prehistorical and Classical Antiquities of the Greek Ministry of Culture. The surrounding parkland is fenced, but the traveler can visit it free of charge at any time.
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.
