Sofia is the capital and the largest city of Bulgaria. It is located at the foot of Mount Vitosha in the western part of the country. Many of the major universities, cultural institutions, and businesses of Bulgaria are concentrated in Sofia.
Green areas
The city has an extensive green belt. There are four principal parks – Borisova gradina in the city center and the Southern, Western and Northern parks, as well as several other smaller parks.
Culture
Sofia concentrates the cultural life of Bulgaria. There are plenty of opportunities to diversify the evenings or the spare time of the visitors of the city. Best choices are among watching a theatre play (for example in the Ivan Vazov National Theatre), visiting an exhibition in one of the museums or galleries or going to the National Opera and Ballet.
