Cesenatico is a port town with about 20,000 inhabitants on the Adriatic coast of Italy. It is located in the province of Forlì-Cesena in the region of Emilia-Romagna, about 30 km south of Ravenna. Cesenatico's port canal was surveyed and drawn by Leonardo da Vinci at the request of Cesare Borgia, as part of his plans to fortify the nearby town of Cesena.
