Gloucester Cathedral: Hogwarts corridors beneath fan vaults
Gloucester Cathedral contributes the Great Cloister, the filmed Hogwarts corridor space familiar from the series. Its medieval fan vaulting gives these passages a distinct visual identity, making Gloucester more specific than a generic cathedral entry. The location belongs on the map because the architecture remains legible as a screen setting even when the fictional school combines material from several real buildings.
The Great Cloister’s role is best compared with Durham Cathedral’s cloisters. Both contribute Hogwarts courtyard or corridor imagery, but Gloucester is defined by its fan-vaulted cloister and its documented use in the first, second and sixth films. Durham, by contrast, also supplies the Chapter House as Professor McGonagall’s classroom. These are related locations, not interchangeable versions of one exact scene.
The cathedral is reused here as an existing verified Place rather than treated as a duplicate Potter attraction. That keeps the map focused on the filmed area and avoids implying that the whole cathedral was transformed into Hogwarts. Because access can depend on current cathedral arrangements, confirm visiting conditions with the linked Place before making the cloister central to a trip.
