These amazing images show the world's largest ever cruise liner taking shape, complete with 'beach pool', shopping mall, rock-climbing walls, outdoor ampitheatre, and New York-style loft suites.
The state-of-the-art 'travelling city' is being built on dry-docks in Finland.
Built for Royal Caribbean International, when Oasis of the Seas launches next November, she will be the largest and most revolutionary cruise ship in the world.
The liner will span 16 decks, encompass 220,000 gross registered tons (GRT), carry 5,400 guests and feature 2,700 staterooms.
Oasis of the Seas will be the first ship to tout the cruise line's new neighborhood concept of seven distinct themed areas, which include Central Park, Boardwalk, the Royal Promenade, the Pool and Sports Zone, Vitality at Sea Spa and Fitness Center, Entertainment Place and Youth Zone.
Work on the super-cruise-liner is progressing full steam ahead at the Aker Yards of Turku - one of only a few shipyards capable of constructing a ship this size.
Almost 1200 feet long, 154 foot wide and rising 213 feet above the water line, the Oasis of the Seas will be able to host 3,000 crew to service every passenger's need.
Adam Goldstein, CEO of Royal Caribbean International, said: 'In essence, we are the brand that delivers the "wow" and we have with this ship.'
In addition to the sheer size of the Oasis of the Seas, this £750 million liner will offer its thousands of passengers a number of 'firsts'.
The introduction of 28 two-level New York-style loft suites which have never been seen before on an ocean going liner will redefine cruise ship accommodation.
Mr Goldstein believes innovation is crucial in attracting and retaining guests.
'It literally means that we are constantly coming up with things,' he said.
'I can't imagine stagnating. It's in our DNA to keep coming up with things. And Oasis allows us to crystallise the platform.'
For entertainment, the liner will feature a 'zip-line', which is similar to the assault course rope lines that span across water and over valleys.
The zip-line on the Oasis of the Seas will allow passengers to face a sheer drop to the seas, guaranteeing an exhilarating experience.
But, most impressively is the introduction of seven special 'zones', each with its own unique character and style. Of all these areas, the standout zone will be the aptly named 'Central Park'.
Built into the middle of the ship, this football pitched sized area will literally be a park in the centre of the ship.
Protected from the weather by a clear perspexed screen to let in the light, the Central Park area will be themed on Caribbean plants and foliage, to reflect the area which the ship will eventually will cruise in.
Designed by British firm Atkins Limited, the park zone will have distinct restaurants, bars and boutique shops, bringing the floating city idea to reality.
It will also boast a rock wall, over 15 restaurants and bars, a casino, a theatre, two night-clubs and the largest freshwater pool on any cruise liner.
The ship will sail from her home port of Port Everglades in Fort Lauderdale in Florida. In 2010, she will be joined by a sister ship, Allure of the Seas.
