The gunports were sealed by lids suspended on hinges. They were opened and closed from the inside with rope lanyards. They are shaped to follow the curve of the hull. The current gunports are all replicas made from teak, fastened with brass screws. Originally the gunports would have been made from oak or elm.
Early photographs of Victory show a high number of the gunports on the lower and middle decks were fitted with small glazed windows.
