Day 1 — Sofia: cathedrals, antiquity, and the historic center
🚶 The first day is best devoted to the Sofia that reveals itself in layers — Byzantine, Ottoman, Bulgarian, and already quite a modern European capital. Start at Alexander Nevsky Square and the patriarchal cathedral of the same name: the huge golden dome is visible from afar, and the church itself impresses not only with its scale but also with the special solemnity of the space. Nearby, it is convenient to see Saint Sofia Basilica and walk toward the area around the National Assembly and Sofia University, where the city looks more ceremonial and “capital-like.” Then head toward the Saint George Rotunda — a small brick church hidden among later urban buildings; contrasts like these explain Sofia’s character especially well. After that, it makes sense to visit the National Archaeological Museum to gather the historical context, and then walk to Vitosha Boulevard and Saint Nedelya Square. Plan a relaxed pace for the whole day: the walking part in the center with 1–2 interiors and a museum usually takes 6–8 hours including a coffee break and lunch. Between the main points in the center, 5–15 minutes on foot is usually enough, so the day feels full but without transport overload.
