From Kiáton, 13km/8mi southeast of Xylókastron, a road branches off on the right to the village of Vasilikó (6km/4mi), and the site of ancient Sikyon, birthplace of the sculptor Lysippos. To the left of the access road are the foundations of a temple of Apollo or Artemis. South of this can be seen the remains of a stoa, a bouleuterion and a
gymnasion. On the slopes of the acropolis is a theater.
Sikyon features an Archeological Site and Museum that is located in a Roman bath-house. It features pavement mosaics, sculptures and other decorative artifacts.
