Karst or Kras in Slovenian, derives from the Indo-European root "kar", that is rock, stone. 

It is drammaticaly known as the scene of violent battles in the First World War.
It is now a border territory, with an eye to the Adriatic Sea and the other to the harsh karst promontory. Surrounded by the scents of the Mediterranean, it is bright and shining more than ever when the air is made clear by the bora wind.
Famous for its landscapes, cliffs overlooking the sea and the soft hills of the hinterland where you can enjoy magnificent views, the Karst is a particularly precious territory under the naturalistic profile. Because of the geomorphological peculiarities, the caves, the sinkholes and the valleys that the water and the underground courses of the rivers have dug into the rock, the area is a paradise for geologists and, for the extraordinary variety of vegetation, that of botanists.

It is a limestone plateau that extends geographically from the Julian Prealps in the north-east of Italy, surrounds the Adriatic Sea through Slovenia and reaches the Velebit massif in the extreme north-west of Croatia.
