Sofia Metro Inside Out

A rare and audacious act of documentation. Over almost a decade, anonymous photographer Errorflict and his steadfast accomplice Seco slipped past guards, outsmarted surveillance, and navigated Sofia’s heavily secured, Soviet-era subway system, turning an untouchable fortress into a visual archive.

This 296-page photo book blends cinematic photography with wild tales of escape, loss, and triumph. It reveals the stark, surreal, and strangely intimate beauty of a city’s unseen heart, where few have dared to go and even fewer have managed to return with proof.
