Discover one of the oldest cities in Europe on a full-day guided tour of Sofia, and admire UNESCO-listed monuments, relics of the communist regime, and testaments to the city’s rich artistic heritage. Following a pick-up from your hotel, go to the medieval Orthodox Boyana Church on the outskirts of the city. Built in the 10th and 11th centuries, the church was inscribed by UNESCO in 1979 for its exceptional frescoes and contribution to understanding medieval Bulgarian culture. Continue to the National Historical Museum to gaze at artifacts of Balkan history. Then, go to Pancharevo Lake for lunch and enjoy the peaceful atmosphere of the artificial reservoir at the end of Pancharevo Gorge. Travel into the city center to see the modern National Palace of Culture, and walk to the ancient St. George Rotunda, considered the oldest building in Sofia. Pass the National Archeological Museum, housed in a former Ottoman mosque, and see the city’s only remaining functioning mosque at the 16th-century Banya Bashi Mosque. Another beautiful religious monument is St Nedelya Church, one of the landmarks of the city, while the ornate Ivan Vazov National Theatre showcases the city's more secular side. Wander past the former Royal Palace along Tsar Osvoboditel Boulevard to the Russian Church. Admire the parliament building in National Assembly Square, dominated by the impressive monument to Tsar Osvoboditel (King Liberator), erected in 1907.
