Olynthos

Olynthus is an ancient city in present-day Chalcidice, Greece. It was built mostly on two flat-topped hills 30–40m in height, in a fertile plain at the head of the Gulf of Torone, near the neck of the peninsula of Pallene, about 2.5 kilometers from the sea, and about 60 stadia from Poteidaea.

The city flourished between 432 BC and its destruction by Philip II of Macedon in 348 BCE. It was finally abandoned in 316 BCE. Excavations were conducted across four seasons, spanning from 1928 to 1938. Artefacts found during the excavations of the site are exhibited in the Archaeological Museum of Olynthos.
