Facebook is bringing new meaning to Scandinavian cool.

CEO Mark Zuckerberg proudly posted photos Wednesday of the company's massive data center, just 70 miles from the Arctic Circle.

Located in Luleå, in northern Sweden, the building opened in 2013 and is a mix between a Cold War bunker and a futuristic, science fiction movie. It's so vast that employees get around on scooters, Zuckerberg wrote.

The center is a "key part" of what keeps Facebook running for its 1.71 billion users, Zuckerberg said.

The temperature in Luleå is below 50 degrees most days, so Facebook uses large fans to bring in the chilly outside air as an energy efficient way to cool thousands of warm servers that are continuously operating.

Hydro-electric plants on local rivers also provide a "reliable and renewable power source," Zuckerberg said, allowing the Swedish operation to use 40 percent less power than a typical data center.

Earlier this month, Facebook announced its next data center will be built in Los Lunas, New Mexico. The social network also has data centers in Clonee, Ireland; Prineville, Oregon; Forest City, North Carolina; Altoona, Iowa; and Fort Worth, Texas.

If you 'liked' these photos, expect more from Zuckerberg.

"Over the next few months, I'm going to start posting some rare photos of the most advanced technology Facebook is building around the world," he wrote.
