Sofia, Bulgaria's Capital: Location in the Western Sofia Basin

Sofia, Bulgaria's capital and largest city, lies in the western part of the country within the Sofia Basin. It is encircled by mountains: Vitosha to the south, Lyulin to the west, and the Balkan Mountains (Stara Planina) to the north. This basin setting influences its climate (colder winters, hotter summers than coastal areas) and has historically made it a strategic crossroads. Today, Sofia is the nation's administrative, economic, cultural, and transport hub.
