Pontarddulais Town Council is twinned with Cobh, County Cork in the Republic of Ireland. Cobh is located on Great Island, which is in a prominent position at the heart of Cork Harbour, 25km from the City of Cork. The island and the town are linked to the mainland by the R624, which runs Southwards from the N25 and by a direct rail link to Kent Station in Cork City.
The town has a proud maritime heritage. Cobh was the main embarkation point for millions of Irish who left their homeland in the nineteenth and twentieth centuries in search of a better life. Cobh was the final stop off for the doomed Titanic on its fatal voyage; 123 passengers boarded the ship in Cobh. Cobh is also the final resting place for many of the victims of the Lusitania sinking in 1915.
