A historic cast iron cannon has been uncovered during ongoing transformation works in Queen’s Gardens.
The find was made on Friday 13 February during excavation for an attenuation tank, when local contractors, C R Reynolds discovered the large object embedded beneath ground level.
Early assessments from the Archaeology team suggest the cannon may date from the 17th to 18th century, although this broad timeframe will be refined as investigations progress. The cannon measures approximately 2.6 metres in length and is estimated to weigh over a tonne.
Initial observations indicate the cannon had been decommissioned, with the nozzle deliberately capped. Archaeologists believe it was likely repurposed as a mooring post, a common practice in the late 19th and early 20th centuries, before being pushed into the dock area prior to it being infilled in the 1930s.
Further excavation will continue in the immediate area to continue as part of the ongoing works.

Peter Connelly, of Humber Field Archaeology, said: “This is a fascinating discovery that offers a glimpse into Hull’s maritime and military past. Our archaeology team is now carrying out detailed assessments and we’ll be able to share more once their work is complete.
“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 will be fully assessed and recorded off-site. More information will be provided once archaeological analysis is complete.
