For a time, a century ago, Belfast was the world's leading industrial city, anchored by the biggest shipyard in the world, and there it created the biggest man-made moving object in history....the ocean liner Titanic. Today Belfast is more about the spaces Titanic left behind. At the 880 foot-long Thompson Graving Dock, where Titanic was hauled to check and clean its hull and fit the propellers, Colin Cobb, a self-professed Titanorak who runs Titanic Walking Tours, brings it home sharing that the dock could hold 21 million gallons of water, or, in terms better understood in Ireland, 168 million pints of Guinness.
