Mendi is an ancient city of Halkidiki Greece, located in the middle of Kassandra peninsula, on its western side. The area is believed to have been inhabited from 9th till 4th century BC. The name of the city derives from the plant minthi (peppermint), which was found in abundance in the area. Mendi in Halkidiki Greece is the birthplace of a famous Greek sculptor, called Paeonius, who sculpted the statue of Nike in Olympia Peloponnisos. Mendi was a very powerful city, as its citizens were occupied with timber trade and wine production, known as "Mendaios" wine. In the area of Mendi major deposits of gold and silver were found, something that indicates the circulation of coins, used for trading.
The archaeological site is located on a hill above sea level. On the top of the hill the acropolis of Mendi is located, known as "Vigla". Some underground storage spaces were found in the area, containing ceramics. In the plateau, known also as Glade, some remnants of the walls of the ancient city were found. In seaside area of the town, called "Suburb" by Thukidides, some parts of houses and roads, that date back to 9th - 4th century BC were also discovered. On the beach of Mendi hotel, an ancient cemetery was found, with 241 entombments, mainly from babies and young children, which date back to 8th - 6th century BC.
The vessels found in Mendi were representative of the ceramic style of Halkidiki. At sandy cape Posidi, 4 km west of Mendi, the sanctuary of the ancient town of Mendi was found. The excavations revealed several buildings, including the temple of Poseidon. Another of these buildings, an arched building, dating back to 6th century BC, is considered to be one of the most ancient sanctuaries in Greece.
Mendi participated actively in Delian league and the Peloponnesian war. The town also had an alliance with Athens, but during the Pelloponnesian war it defected and this caused its siege and pillage from Athenians. In the middle of 4th century BC Mendi was taken by Philipos II and it gradually declined.
