This Sunday night sees the 107th anniversary of the sinking of the Titanic.
More than 2,200 people were on board, and more than 1,500 lost their lives that fateful night.
Ivan went to Titanic Belfast, a visitor centre in East Belfast beside the Harland and Wolff shipyard where the ship was built between 1908 and 1912.
Have a listen to Ivan's tour of the centre with his tourguide, Shirley
