Sofia (София) is the capital of Bulgaria. It is also the biggest city in the country with about 2 million citizens (including suburbs). Today, Sofia is a dynamic European capital, distinguished by its unique combination of European and Communist-style architecture as well as many beautiful Orthodox churches. Furthermore, it claims to be one of the few European capitals with beautiful scenery and a developed ski-resort so close to it - the Vitosha mountain.
Sofia was founded around 2,500 years ago. Over the centuries, it has been given several names — Serdika, Sredets and the remains of the old cities can still be viewed today.
