Sofia is the capital of Bulgaria and the largest city in the Balkans (population 1.3 million) — a city of 7,000 years of continuous settlement, built in a mountain basin surrounded by Vitosha Mountain (2,290 m, the closest mountain to any European capital), with a history that has been shaped by the Thracians, Romans, Byzantines, Bulgarians, Ottomans and Soviets, leaving one of the most layered and visually contradictory urban environments in Europe. Sofia (called Serdica by the Romans — Emperor Constantine the Great, who was born in the Roman Balkans (modern Serbia), declared "Serdica is my Rome" and considered moving the capital of the Empire from Rome to Serdica before choosing Constantinople) has been beneath every major empire that passed through the Balkans. The Alexander Nevsky Cathedral (the most important Bulgarian Orthodox church, built 1882-1912 to commemorate the Russian soldiers who died liberating Bulgaria from Ottoman rule in the 1877-1878 Russo-Turkish War; the largest Eastern Orthodox cathedral in the world after the Saint Sophia in Kyiv; the golden dome is the defining element of the Sofia skyline), the Roman ruins visible throughout the city centre (the Serdica archaeological complex under the National Archaeological Museum, the visible Roman forum beneath the Sofia Hotel Balkan and the rotunda of St. George), and the Rila Monastery day trip (UNESCO World Heritage — the most significant Bulgarian Orthodox monastery, 120 km south of Sofia, one of the finest examples of Bulgarian National Revival architecture) define the Sofia experience.
The Alexander Nevsky Cathedral (Катедрален храм "Св. Александър Невски" — built 1882-1912 in Bulgarian Neo-Byzantine style; the largest Orthodox cathedral in Bulgaria and among the largest in Eastern Europe; built as a national memorial to the 200,000 Russian soldiers killed in the 1877-1878 Russo-Turkish War that liberated Bulgaria from 500 years of Ottoman rule (the Russo-Turkish War of 1877-1878 was fought after a Bulgarian uprising in 1876 was suppressed with extraordinary brutality by Ottoman irregular forces — the "Bulgarian Horrors" that William Gladstone wrote about and that brought Russia into the war); the cathedral seats 5,000 people; the painted murals inside (by Bulgarian and Russian painters) depict the life of St. Alexander Nevsky (the 13th-century Russian military hero who defeated the Teutonic Knights); the crypt museum contains Bulgaria's most significant collection of Orthodox icons and religious art (6th-19th century icons, vestments and ecclesiastical metalwork)).

🎫 Book tickets via GetYourGuideThe Rila Gorge (the Rilska River valley surrounding the monastery — the reason St. John of Rila chose this specific location: the 700 m deep gorge, accessible only from one direction, with the river running through it, created the combination of isolation, clean water and defensible terrain that hermits and then monastery founders sought throughout the Byzantine world; the gorge walk (the 2 km walk from the monastery along the Rilska River to the Cave of St. John of Rila — the cave where the founding hermit lived in the 10th century; his bones were kept in the monastery and their transfer to Sofia in the 13th century and back to the monastery was a major political event of Bulgarian medieval history; the cave is still a pilgrimage site with a permanent flame at the entrance).
