meant that in 1972 its working mechanism was in such a parlous state that the organ had to be abandoned as unplayable. After a silence of fourteen years it was eventually restored by Mander in 1984–86. Today it is widely regarded as a very special part of the heritage of English organs and it is the only surviving example of an English classical, rather than romantic, cathedral instrument. Nave Organ Source: Details of the Nave Organ from the National Pipe Organ Register The Nave Organ was a gift of the Poling Charitable Trust, the Nave Organ was built by Mander as part of the organ project in 1986. With one manual of six stops, plus a single pedal stop, the Nave Organ is designed to reinforce the presence of the main organ in the nave, or for use in its own right for in the "nave-only" services. The Nave Organ can be played either from its own console downstairs, or direct from the main organ.

It is usually housed in the Lady chapel, and accompanies services held in that part of the cathedral. It is, however, readily moveable and is frequently used for concerts of baroque music in the nave. Hurdis Organ Source: Details of the Hurdis Organ from the National Pipe Organ Register The Hurdis Organ was built c.1780 at least partly by the Reverend James Hurdis, who was headmaster of the Prebendal School who went on to be Professor of Poetry at Oxford University. In 1947, the Hurdis family gave the organ to the Prebendal School who, in turn deposited it on loan to the cathedral. It is currently housed in the retrochoir, where it is regularly used to accompany services at the Shrine of St. Richard. Allen Organ The Allen Organ was brought into the cathedral in 1972, at the time when the main organ was abandoned, and was used to accompany all main services until 1986 when the main organ came back into use. Thereafter, the Allen Organ was repositioned in the triforium at the west end of the cathedral as a concert organ. It is one of the earliest digital electronic organs in this country and continues to play
