100 years since Titanic set sail
It was 100 years ago that the Titanic, the largest passenger ship ever made at the time, was launched in Belfast where it was built.
The ship didn't make its doomed voyage from Southampton to New York until the following year, 1912.
To mark the anniversary the people of Belfast are having a massive celebration.
The commemoration begins at City Hall with photographs remembering the Titanic and all those who built it.
