Salento

Salento (Salentu in Salentino dialect) is the southeastern peninsular extension of the Apulia (Puglia) region into the Mediterranean Sea, in southeastern-most Italy. It is a sub-peninsula of the Italian Peninsula, sometimes described as the "heel" of the Italian "boot".
It encompasses the entire administrative area of the province of Lecce, a large part of the province of Brindisi and part of that of Taranto.
The peninsula is also known as Terra d'Otranto, and in ancient times was called variously Messapia, Calabria, and Salentina.

Salento peninsula is composed of limestone, dividing the Adriatic Sea from the Ionian Sea. Known also as "peninsula salentina", from a geo-morphologic point of view it encompasses the land borders between Ionian and the Adriatic Seas, to the “Messapic threshold”, a depression that runs along the Taranto-Ostuni line and separates it from the Murge.
