The modern village of Sikyon is occupying the lower plateau of the new city that Demetrios Poliorketes built in 303 BC. It is here that Pausanias came around 150 AD and made his descriptions. The village also known as Vasiliko has readopted the official name Sikyon. Majestically situated on a very high elevation of the ground on the Acropolis of the old city, it overlooks the Corinthian Gulf and the modern city of Kiato or Sikionia.
The views from the village are simply great. Underneath is the big fertile plain where oranges, lemons, apricots, peaches, currants, olive trees, almonds, etc. are cultivated and across the sea gulf the mountains of Gerania, Kithaeron, Helikon, and Parnassos can be seen. It is most beautiful at the sunset or sunrise.

The theater of Sikyon, one of the biggest of continental Greece, was built at the end of 4th century BC in an ideal natural place and was excavated by the American School of Classical studies in 1887 - 1891. The orchestra has 20m diameter, surrounded by a drain, and the cavea is 125m across. The lower diazoma could be reached by two vaulted passages on either side, as well as the 16 staircases from the parodoi. They are 50 tiers of seats, most hollowed out of the rock (not completly excavated), divided into 15 wedges. The front seats have backs, armrests and sculptured feet. The stage building had as a facade a Doric portico of 13 columns. Polibious tell us that the Achaean League met here in 168 BC and most probably was used also for political meetings.
Today every summer in August, theatrical performances take place here.
