Terra-Peninsula

Terra-peninsula (noun): A distinct tract of habitable or low-lying land that projects into, or is bordered on three sides by, severe geographical barriers such as mountain ranges, deserts, or extreme climate zones, isolating it from the surrounding mainland. It is only passable from 1 side, or by boat.

Bordered and enclosed on three sides by the towering Carpathian Mountains, Wallachia historically functioned as a protected terra-peninsula of fertile lowlands.
