The Guildhall was opened on 13 February 1937 and was designed to complement the rest of the Civic Suite. It features a large and unique pipe organ which was built into it from new. The organ has two distinct consoles and is a fully featured classical concert organ on the one hand, and also a large theatre organ on the other. The two consoles share the same body of approximately 4000 pipes which are housed in chambers above the proscenium arch. It was the largest organ made by its builder, John Compton.
