The Italian border refers to the geographical boundaries that separate Italy from its neighboring countries. Italy shares its borders with France, Switzerland, Austria, and Slovenia. These borders are marked by natural features like mountains and rivers, as well as man-made demarcations. The total length of the Italian border is approximately 1,400 kilometers. The Alps mountain range forms a significant part of the northern border, while the Adriatic Sea lies to the east. These borders play a crucial role in trade, travel, and cultural exchange between Italy and its neighbors.
