You step out from the shadow of Saint Nedelya Church into a city that shows its age in layers—Roman stone rubbing shoulders with 19th‑century boulevards and the green sweep of Boris’ Garden. The walk moves quickly: a compact thread through Serdica’s excavated streets, past the quiet red brick of the St. George Rotunda, and under the gleam of Alexander Nevsky’s domes.

History
Sofia sits atop Serdica, a Roman town that left streets and basilica foundations visible under the modern city; the Sofia University Observatory dates to 1892 and played a key role in regional astronomy.
Conservation
Minimize light pollution around the observatory by avoiding flash photography at night and stick to marked paths in Boris’ Garden to protect trees and nesting birds.
