During construction, a massive engineering feat for the time: Construction of the Titanic started on the last day of March 1909 at the Harland and Wolf shipyard in the Irish city of Belfast, and it would take more than two years. Harland and Wolf had been building ships for the White Star Line for more than four decades. The Olympic vessels, for their part, were the largest ever built at that point. Artist's rendition of the stricken ship slipping into the depths, still with over 1,000 souls aboard. Yet, by today's standards, she was small..... Royal Carribean's Oasis of the Seas is FIVE TIMES the size of the Titanic!
