has the town's Tourist Information Office, and, until the Corn Exchange was built in 1856, the open area under the hall was used for the town's corn market. The hall is open to all residents as a venue for private hire. Corn Exchange The Corn Exchange building dates to 1856. The iron arches supporting the roof of the building were cast at the Wilders foundry on Goldsmiths Lane. The Building has seen a variety of uses since its construction but until the outbreak of the First World War the building hosted the grain exchange and weekly corn market. In the inter-war years uses included boxing, cinema and auctions. After the Second World War the Social Security Ministry used the Building as a food and unemployment office before it fell into disuse. It was purchased by the Sinodun players in 1975 for use as a theatre. They dedicated it to Agatha Christie, who was president of the society from 1951 to 1976. The Corn Exchange has productions put on by the Sinodun players as well as providing space for other dramatics groups. The building functions as the town cinema. The Corn Exchange & Sinodun Players were awarded the Queen's Award for Voluntary Service in 2020.
