Cruise ships are basically giant floating cities. How do you build a giant floating city? Well, it’s pretty much like playing with Lego bricks. This time lapse shows the construction process of building AIDA Cruises’ new flagship in Nagasaki: the AIDAprima. The AIDAprima can hold up to 3,300 passengers with 900 crew members and is nearly 1,000 feet long. The ship cost $645 million to build and seeing it get put together almost makes it worth the sticker price.
