Port of Dublin launched a special communication campaign featuring dozens of photographs from the 1920s to the 1960s. The images, disclosed now for the first time, show the life and working of the port of Dublin during the first half of the 20th century. The archive of the port of Dublin contains 75 000 photographs and 30 000 engineering drawings, besides maps and other documents. The origin of the disclosed photographs remains a mystery and the port has made a public call for members of the docklands community to help identify the author. This action fosters a new engagement with the local community, highlighting the port identity of the city.
