[citation needed] Its strategic location and rich resources developed Toroni into one of the most significant cities in Chalkidiki, giving its name to the gulf that forms between Pallene and Sithonia peninsulas.

During the Greco-Persian Wars it allied with the Persians, who as a reward gave Olynthus to Kritoboulos, a local ruler, in 479 and later became part of the Athenaean League, contributing one of the highest taxes that reached 12 Attic talents per year, giving an indication of its prosperity.

It was besieged by the Athenian General Timotheus by means of cutters attached to the top of masts made to cut open sandbags used in the city's defence.

In 168 BC the Romans invaded and the city decayed, but did not cease to exist, as indicated by the harbour fort, Lecythus, which was rebuilt during the Byzantine era.

Traces of prehistoric settlements of the 3rd century BC and many other ancient remains, including early Christian and Byzantine temples, and castles are evidence that the area was inhabited continuously from the Neolithic era.

In the Acropolis and the main city, parts of the fortification are clearly visible along with dispread stone blocks, ancient pantiles and broken pottery which are found everywhere.

Unfortunately, most of the city's buildings were destroyed in the beginning of the 20th century, when the Ottoman authorities hired an Italian engineer in order to collect the stone blocks to use them as paving in roads.
