Gloucester — La Fédération sur le territoire

Gloucester — the cathedral city at the gateway to the Cotswolds — is two hours from Mayfair by driver. Gloucester Cathedral's Norman nave and fan-vaulted cloisters (used as a Harry Potter filming location) are among the finest mediaeval interiors in England; the historic Docks, with their Victorian warehouses converted to restaurants and galleries, complete a half-day. The Federation typically combines Gloucester with a Cotswolds loop via Cheltenham's Regency crescents and Broadway village.
