Glasgow Cathedral Festival returns from 18–21 September 2025, with a bold and celebratory programme marking Glasgow 850. Inspired by the city’s reputation as a place of community and invention, this year’s festival draws together cultural and scientific influences across a range of artforms: from established classical music favourites to cutting-edge contemporary sounds, and intimate theatre to immersive, cult cinema. Within the ancient walls of a building steeped in history, GCF once again fuses tradition with innovation to present new experiences for diverse audiences—reflecting both the legacy and the potential of a city shaped by its people.
