Bradford Council is celebrating the heritage of two 10ft cannons by putting them on temporary display in Bradford city centre.
As part of World Heritage Day, the cannons will be transported to Centenary Square, where they will be on show in front of the main entrance to Bradford City Hall on Wednesday 18 April between 9am and 2pm.
People will be able to get close to the cannons, take selfies and learn about the history of these weapons at the event.
The story of the cannons, which are to eventually go on display in Roberts Park, Saltaire, dates back more than 150 years to the Napoleonic wars.
