Cork Harbour, at the mouth of the River Lee, is one of the largest natural harbours in the world. Located close to Cork City, Cork Harbour is a popular attraction for both visiting tourists and residents. The harbour and the surrounding towns hold many secrets, and those who know the area tell tales of the families who once lived there, and the industries that they were part of.

Known for its wonderful array of islands, of which Great Island is the largest, Cork has a longstanding place in the community. Cork authors Kieran McCarthy and Daniel Breen uncover the distinct history surrounding Cork Harbour's past through a selection of old colour postcards and prints, matched with modern images, in order to show just what has changed and what has stayed the same in Cork Harbour Through Time.
