"Punta Meliso" promontory (the ancient "Promontorium lapygium" or "Sallentinum") is the southeastern extremity of Italy — traditionally considered the lowest point of the geographical "heel" of Italian peninsula, as well as the meeting point of the waters from the Adriatic Sea and the Ionian Sea. But Leuca is a bay so there's another promontory called Punta Ristola challenging this geographical particularity. According to Google Earth, Punta Ristola, at 39° 47′ 22.96″ N, is approximately 440 meters south of Punta Meliso, at 39° 47′ 37.73″ N.
