A decade ago, the New-Zealand-based Antarctic Heritage Trust took on a rather challenging project: To restore four Antarctic explorer's huts built nearly a century earlier. Utilized by British explorers led by Ernest Shackleton and Captain Robert Falcon Scott, the structures served as base camps—and were the last buildings many of the ill-fated men ever occupied.

The restorers had their work cut out for them. Here's what one of the structures looked like in 2005:

Here's the same building, now cleared of snow, being stripped and rebuilt by the team:

Here in 2015, ten long years after they began the project, the team's work is complete. And it is amazing how much stuff has survived inside the structures. "Luckily," reports National Geographic, "the extreme cold preserved many of the huts' artifacts—newspapers, scientific equipment, furniture, cans of food, even a stuffed penguin—in place."

In the video below you'll get to look around inside the amazingly well-preserved, not to mention well-restored, interior. 

And if you're wondering how these structures were built in the first place—Antarctica isn't exactly a timber-rich environment—they were originally designed and prefabricated in London, then broken down, shipped, and rebuilt on-site. Pretty impressive considering it was the early 1900s.
