1. Titanic Belfast
The Titanic Belfast visitor attraction extends over nine galleries, with multiple dimensions to the exhibition. Drawing together special effects, dark rides, full-scale reconstructions and innovative interactive features you will explore the Titanic story in a fresh and insightful way from her conception in Belfast in the early 1900s, through her construction and launch, to her infamous maiden voyage and catastrophic demise. The journey goes beyond the aftermath of the sinking, to the discovery of the wreck and continues into the present day in the Ocean Exploration Centre. Photo: Tripadvisor
