After a build time of 32 months, Harmony of the Seas first set sail on 15 May 2016 from the STX France docks in Saint-Nazaire. The ship's maiden voyage departed from Southampton on 29 May and arrived at its summer home port of Barcelona on 5 June. Harmony of the Seas has 2,747 staterooms to accommodate over 5,479 guests and 2,100 crew members.
Now let’s take a closer look at the world’s largest passenger ship.
 

Harmony of the Seas, an Oasis-class cruise ship, was delivered last Sunday and is ready to set sail. With a gross tonnage of 227,700 GT, she is the largest cruise ship ever built, surpassing her older sisters Oasis of the Seas and Allure of the Seas by some 2,000 gross tons, as well as 2.15 metres (7.1 ft) in length. It was constructed at the Chantiers de l'Atlantique shipyard in Saint-Nazaire, France where thousands of people gathered to see her off and now she's on her way to Southampton, England.
