Santa Maria di Leuca, often spelled simply Leuca (, from Leukos, "white"), is a frazione of the comune of Castrignano del Capo, in the Salento peninsula (Apulia), southern Italy. A part of the town once belonged to the comune of Gagliano del Capo. The territory between Otranto and Santa Maria di Leuca has become a Regional Natural Coastal Park of "Costa Otranto - Santa Maria di Leuca e Bosco di Tricase". In this area, in the comune of Gagliano Del Capo, is located Ciolo. Description Santa Maria di Leuca is famous for its iconic lighthouse. With its height of 47 metres, and position at 102 metres above sea level, is the second most important lighthouse in Italy, after Genova. Next to the lighthouse is the large Sanctuary, or Basilica, De Finibus Terrae ("End of the Land", 1720-1755), built to commemorate the passage of St. Peter here during his travel to Italy. It is devoted to Saint Mary (from whom the town gets the name Santa Maria di Leuca). It lies on the former site of a Greek temple dedicated to Athena. The edifice has a fortified structure, and during its existence it sustained several assaults by Algerian pirates. In the same site, a Corinthian column was erected in 1939 to celebrate the construction of the Apulian Aqueduct (Acquedotto Pugliese). The basilica is connected to the port through a 284-step staircase. 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. After World War II the town hosted Jewish Holocaust survivors for two years (1946-1948), giving them warm hospitality. Since October 2006 its territory is part of the Regional Park "Costa Otranto - Santa Maria di Leuca e Bosco di Tricase". Santa Maria di Leuca's littoral is marked by numerous grottoes with Latin and Greek inscriptions. Also famous are the 19th century patrician villas (c. 43 in number). Not far off Punta Ristola, at c. 85 m of depth, lies the shipwreck of the Italian submarine
