The capital of Northern Ireland is a tourist destination of titanic proportions, but not in a way you would normally imagine. Despite having an area of only 44 square miles, what makes the city a big deal is the Titanic Museum. This attraction features the ill-fated ocean liner that sunk as spectacularly as it was huge during the early 20th century. The city has also become a giant in the entertainment industry, thanks to its use as a "Game of Thrones" filming location. Top-class restaurants and a vibrant nightlife scene also make Belfast a good destination for the casual traveler.
