The famous Unesco-recognised Semmering Railway in Europe forms an important section of the Sudbahn, a railway line that passes through picturesque parts of Austria, Slovenia and Italy on its journey from Vienna to Trieste on the Adriatic Sea.
This railway from the Austrian capital to the port of Trieste in northeast Italy has long been a strategic route and a vital link between Central Europe and the Mediterranean Sea. From 1832 to 1918, Trieste was part of the Austro-Hungarian Empire and was linked to Vienna by a railway line in 1857.
