“Finds like this highlight the rich history beneath our city and the importance of careful excavation as we deliver the Queen’s Gardens transformation.”

The cannon is the latest piece of the city’s history to be uncovered during recent improvement works. In January, part of the Old Town’s medieval walls were discovered in Guildhall Road during work to install a new district heating network. Hull’s walled defences were completed around 1356 with just over four million bricks used during their construction.

The major revamp of Queen’s Gardens is due to be completed in spring. As well as being an attractive open space in its own right, it will form a key part of the Hull Maritime project, linking the refurbished Maritime Museum with the new visitor centre at North End Shipyard, which will also be home to historic former trawler Arctic Corsair and the city’s last surviving Scotch Derrick crane, which has also been restored.
