Olynthos is an ancient city of Chalkidiki, built in a fertile plain, at the edge of Toroni Bay, near the base of the peninsula of Pallini (today Kassandra), at a distance of approximately 60km (11.5km) from Potidea and 4km from the sea. The city of Classical times was constructed according to the Hippodamian system, in an area of 600x300m, with building blocks separated by horizontal and vertical streets. It is noteworthy that the theater of the city has not been found. The houses had two floors, with an inner courtyard. To the south was the market and to the east the houses of the rich. Among the villas that were excavated were found mosaic floors, vases, jewelery and clay figurines. The first archaeological finds came to light in 1928. The most recent excavations took place in the 1990s.
