The Potidaea Canal is an artificial waterway located in northern Greece, connecting the Thermaic Gulf to the Sithonia Peninsula. It was constructed to facilitate maritime navigation and trade, allowing ships to bypass the hazardous waters around the Chalkidiki Peninsula. The canal plays a significant role in local transportation and fishing activities. Originally built in ancient times, the canal has undergone various modifications throughout history. It is named after the ancient city of Potidaea, which was strategically important in antiquity. Today, the Potidaea Canal remains a vital link for local fishermen and recreational boating in the region.
