Sofia is not a city you simply see — it is a city you uncover. Layer by layer, it reveals traces of ancient civilizations, empires, and everyday lives that have shaped its character over thousands of years. Beneath modern streets lie the remains of Roman Serdica, while Ottoman mosques, medieval churches, and 19th-century buildings stand side by side, telling the story of a place where different worlds have met and coexisted. As we walk through the city, we move through time — from antiquity to the present — discovering how history, culture, and geography have shaped Sofia into what it is today. This tour is an invitation to experience the city beyond its landmarks — through its layers, its contrasts, and the stories that connect past and present.
