The Slovak border refers to the international boundaries that define the territory of Slovakia. It shares borders with four countries: Austria to the west, Czech Republic to the northwest, Poland to the north, and Ukraine to the east, while Hungary lies to the south. The total length of the border is approximately 1,100 kilometers. The border is characterized by diverse landscapes, including mountains, rivers, and plains. Key geographical features include the Carpathian Mountains in the north and the Danube River in the south. These natural barriers have historically influenced trade, migration, and cultural exchange in the region.
