Sofia

At first glance, Bulgaria's largest city appears to be just another bustling, modern capital, but there are still layers of history to be discovered. The most recent discovery occurred between 2010 and 2012, when a large portion of the ancient city of Serdica was discovered during the construction of a metro station.

The Alexander Nevsky Cathedral, the Saint Sofia Church with its subterranean museum and necropolis, the 4th-century Church of St. George, and the UNESCO-awarded Boyana Church are just a few of the city's most well-known attractions. The National History Museum, which houses some of the world's most famous ancient gold treasures, the National Museum of Natural History, the National Archeology Museum, the National Art Gallery, which is housed in the former royal palace, and the Museum of Socialist Art are all located in Sofia.

Nature lovers will not be disappointed, as Sofia is located at the base of the Vitosha Mountain, which offers hiking and skiing opportunities. When you visit Sofia, you'll find everything from exciting nightlife and affordable lodging to lovely boutiques and charming cobblestone streets.
