The Great Hall has twice been destroyed by fire - during the Great Fire of 1666 and by incendiary bombs in 1940 - but on each occasion the walls and foundations survived and were incorporated in the restored hall. The room is beautifully illuminated by original stained-glass windows and imbued with the rich warmth of the mahogany panelling. Above the main entrance, the Renatus Harris Organ, installed in 1966, is a work of great craftsmanship. This grand Hall is one of the largest in the City of London.
In the Great Hall, 3 phase power is available.
