The Rochester Bridge Trust has provided and maintained crossings of the River Medway for more than 600 years – with the first bridge on the site built almost 2,000 years ago – but there is still much that remains unknown about the organisation among the general public, as visitors to the Bridge Works exhibition will discover. The cathedral crypt will house the main exhibition, taking visitors through the ages as they follow the changing shape of Rochester’s bridges. While across the hall Langdon’s Den – home of education mascot Langdon the Lion – will house a series of fun and educational civil engineering activities for children.
