Surrounded by sprawling parkland, Sofia, the capital and largest city of the Republic of Bulgaria, lies at the foot of popular ski mountain, Vitosha. With a history that stretches over seven millennia, ruin-rich Sofia is one of Europe's oldest cities. The National Historical Museum is one of Eastern Europe's most extensive. Wide, cobblestone boulevards, charming boutiques and truly electrifying nightlife star in this city of 1.3 million. Trolleys, trams and buses traverse the dynamic city.
