Have you ever wanted to decipher secret messages? Join a family activity where you can intercept messages, map hazards on a sea chart and even make up your own secret code.
You'll learn about some of the skills intelligence officers and spies have used in the past.
Along the way, you'll also find out about the dangers that have surrounded HMS Belfast at sea during her long history in the Royal Navy.
This activity is in association with Maths on Toast who help to co-ordinate community events designed to make maths fun.
Drop-in events are suitable for all ages with parental supervision.
