Olynthos is an ancient city of Calkidiki, located in a fertile plain in the bay of Toroni near the base of the Kassandra peninsula. The site has been inhabited since the Neolithic Age (5300-4500 BC). In accordance with local mythology, the city was named after Olynthos, son of the river God Strymon.

Since antiquity, the cultivation of the olive was known and widespread in Olynthos. This is due to the particular dry climatic conditions of Chalkidiki and to the highly adaptable local variety (chondrolia).
