Over 5,000 people were in Cobh today for a commemoration service held for all those who died on the Titanic.

The luxury liner left Cork Harbour 100 years ago today on its ill-fated maiden voyage to New York.

President Michael D Higgins told the gathering that it is right that time is taken to remember with respect all those who died on the Titanic and the thousands more whose lives were devastated by the loss of their loved ones in the Atlantic.

Four Titanic stamps, commissioned by An Post, were unveiled at the National Tribute depicting shipbuilder Thomas Andrews, Fr Francis Browne, who photographed the ship, ''Unsinkable'' Molly Brown and Captain Edward J Smith.

Among the dignitaries attending today's ceremony were Minister for State for Northern Ireland Hugo Swire, and Acting British Ambassador Andrew Stanton.

Minister for Agriculture Simon Coveney and Minister for Innovation Sean Sherlock were also in attendance.

President Higgins also carried out an international naval service fleet review from the deck of the LE Eithne.
