Sofia is one of the oldest cities on the Balkans found by the Thracian tribe Serdi. In 29 A.D. Sofia became the capital of the Roman province of Inner Dacia. Through the ages, the city played role as an important trading center in the Byzantine and Bulgarian Empires. Under Ottoman rule, Sofia was the center of Rumelia province. Sofia became the capital of restored Bulgaria in 1879, with a population of only about 12,000. Today many streets, buildings, parks, and even whole neighborhoods preserve the architectural style from the turn of the century. We will explore the compact city center, Boyana Church (UNESCO) and the National History Museum - one of the largest on the Balkans.
