The 100th anniversary of the Titanic's launch has been marked at a commemorative event in Belfast.
A single flare was fired above the city's docklands to signify the exact moment - 12.13pm - 100 years ago when the ill-fated liner rolled down the slipway and touched the water for the first time.
All boats in the area around the Harland and Wolff shipyards, where the pride of the White Star fleet was built, then sounded their horns.
In 1911, thousands of cheering well-wishers gathered at the same place to celebrate the historic moment.
A century on, the mood was again one of celebration at the event on the Queen's Island slipway which focused more on the ship's construction than its fate.
After the flare was fired, crowds clapped for exactly 62 seconds - the length of time it took for the liner to roll down the slipway in 1911.
The Titanic sank on her maiden transatlantic voyage from Southampton 11 months after her launch, with the loss of more than 1,500 lives, when she struck an iceberg.
Among the invited guests at the commemoration were schoolchildren and representatives from the four other cities and towns directly connected to the Titanic story - Cherbourg in France, Cobh (formerly Queenstown) in Co Cork, Liverpool and Southampton.
The Harlandic and Queen's Victoria male voice choirs sang a number of hymns during the half-hour service close to the almost-complete £100 million Titanic visitors centre, which is set to open ahead of next year's centenary of the liner's sinking in 1912.
Earlier, a major new exhibition on the Titanic opened at the nearby Ulster Folk and Transport Museum, boasting some artefacts recovered from the liner that have never been put on public display before.
