Salento is a geographic region at the southern end of the administrative region of Apulia in Southern 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 the past Sallentina. In ancient times it was called variously Calabria or Messapia. The Salento peninsula is composed of limestone, dividing the Gulf of Taranto to the west from the Strait of Otranto on the east, with the Adriatic Sea to the north and the Ionian Sea to the south.
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.
