Description

This description refers to a former cannon barrel located on the southwest side, dating from the mid to late 19th century. The site features two iron bollards, which have a plain square top that transitions to a rounded octagonal shaft. Each bollard is hollow and has a pierced hole on each side. The western bollard is inscribed with the words "Sturges and Co, Bradford, Yorks, Ironworks." These bollards are similar in style to those found around the Graving Dock.

The cannon barrel is positioned upright as a bollard just north of Old Pier House and is notable for being the last remaining in its original location from a set. The other cannons have been removed and mounted on new carriages, such as those displayed at Fort Road Park. It is believed that the cannons are of Dutch origin.
