The Holywell Music Room, with access from Holywell Street, is said to be the oldest, purpose built music room in Europe, and hence England's first concert hall. It was designed by Thomas Camplin, former Vice- Principal of St Edmund Hall, and opened in July 1748. The interior has been restored to a near replica of the original and contains the only surviving Donaldson organ, built in 1790 by John Donaldson of Newcastle.
