Located underneath Langjökull ice cap in the Highlands of Iceland, IceCave will be one of the world's biggest ice structures -- spanning an astonishing 656,984ft -- when it's scheduled for completion in May 2015.
Tour operators working in the area came up with the idea for the elaborate ice cave years ago, long before excavation work began this Spring. By the time the project's finished, the planners expect to have dug up around 75,347sqft of ice.
More than a mere underground passage, IceCave will be an all-in-one entertainment spot, featuring a network of caves and tunnels 98ft deep, with ample room for an exhibition space, ice sculptures, a restaurant, and even a chapel.
It's kinda like Las Vegas' CityCenter, but on a glacier, and less likely to be underwater (mortgage joke).
As trekkers venture deeper into the ice cap's cold heart, the ice will range on a spectrum of white to blue, signifying its age.
