City of Caves is a visitor attraction in Nottingham based on a network of caves, carved out of sandstone that have been variously used over the years as a tannery, public house cellars, and as an air raid shelter. The caves are listed as a scheduled monument by Historic England under the name Caves at Drury Hill, Drury Hill being the medieval street under which they were formerly located until it was demolished to make way for the Broadmarsh Shopping Centre. The newer City of Caves name refers to the fact that the city of Nottingham has hundreds of man-made caves, which have been in use for over a thousand years.
