Immigrants from Euboea settled in Toroni during the 8th BC. century. The city became a member of the Athenian League, until the Spartans captured it. King Philip II of Macedonia occupied the city in 348 BC, while in 168 BC the region fell into the hands of the Romans.
Ancient Toroni was one of the largest and richest cities of Halkidiki.
During the years of Roman occupation and the Byzantine era, the city walls were strengthened to protect it from the sea and the land. They were built with the construction material left over from the ancient acropolis.
Excavations in the area began in 1975 by the Australian Archaeological Institute in Athens. The findings showed that the area had been continuously inhabited since the Early Bronze Age. Some very important vessels were found in the city cemetery. Among them is a magnificent silver jug, dating from the 5th century BC, with engraved jellyfish on the handles, which is now on display in the Archaeological Museum of Thessaloniki.
The visitor can see part of the city walls and ruins from the citadel. The docks of the port, made of huge granite blocks, were discovered at the bottom of the sea. Together with the remains of stone walls, which continue on the coast and were probably the warehouses of the city.
