Geography Polygyros town (pop. 6,121 at the 2011 census) is built in the shape of an amphitheatre on a plateau on the south west side of the mountain Cholomontas. It is south of Greek National Road 16 (Thessaloniki - Arnaia). Polygyros is located SE of Thessaloniki, NE of Nea Moudania, NW of Sithonia and SW of Arnaia.

Climate Polygyros has a temperate climate with relatively cold winters and pleasant summers due to its elevation. Name There are different speculations about the origin of Polygyros' name. Some claim that it comes from the combination of poly (much) and geros (strong), because of the healthy climate. Others believe that the words poly and (sacred) have given the present name, because of an ancient temple in the area. Also an old landowner, named Polyaros, offers a possible etymology. According to another possible etymology, the name derives from poly and gyros (round), possible due to the town's amphitheatric position. Municipality The municipality Polygyros was formed at the 2011 local government reform by the merger of the following 4 former municipalities, that became municipal units: Anthemountas Ormylia Polygyros Zervochoria The municipality has an area of 947.417 km2, the municipal unit 470.933 km2. History Antiquity Some situate in the broader area of modern Polygyros the ancient city of Apollonia. Apollonia was one of the 32 cities, which, under the leadership of the Olynthus, constituted the Koinon ton Chalkideon (Chalkidian League). The Koinon was destroyed in 379 BCE by the Spartans, while in 348 BCE Philipp II of Macedon annexed the whole Chalcidice into the Macedonian Kingdom. In 168 BCE Chalcidice was subjected by the Romans. Byzantine and Ottoman Era The town of Polygyros is first mentioned in a medieval imperial document, chryssovoulon (with golden stamp), of Eastern Roman Emperor Nikephoros III Botaneiates about 1080 CE. In 1430, as the rest of the Eastern Roman Empire, Polygyros was conquered by the Ottomans and belonged to the Sanjak of Thessaloniki. On 17 May 1821 the people of Polygyros rose against the Ottoman authority and managed, temporarily, to expel the Ottoman guard. Polygyros,
