In place of the current Polichrono there was the ancient Neapolis, a colony of the Eretrieans. It is believed to have been established in the middle of the 7th century BC. This city was given many barbarian invasions, with the last of the Huns, which led to its extinction in 540. During the Roman era, Neapolis seems to have been rebuilt in the nearby location of “Frangoklissia”, where remains of a Roman settlement have been marked. In the 11th century, farmers and livestock farmers settled in this area. The latter made the village Polichrono, which was named because of the many flowers that were there. During the Ottoman domination, it was burned and completely destroyed by the Turks. Later few remaining residents returned and built the village from the beginning, which due to verbal corruption received the name Polichrono. During the Ottoman domination, like all other villages on the peninsula, it was taxed under the name of Gaasanfer Aga, while administratively belonged to the tribe of Kalamaria. In 1821 the inhabitants of Polichrono participated in the revolution of Chalkidiki, with the result that the village was destroyed by the Ottoman troops. Among the fighters of 1821 stand out Nicholas Ioannou, Athanasios Andreas and Rigas Adam.
