A Look Inside Mark Zuckerberg's Massive Apocalypse Bunker Within His 100 Million Dollar Hawaii Compound

OFF THE TWO-LANE highway that winds along the northeast side of the Hawaiian island of Kauai, on a quiet stretch of ranchland between the tourist hubs of Kapaa and Hanalei, an enormous, secret construction project is underway.

A 6-foot wall blocks the view from a nearby road fronting the project, where cars slow to try to catch a glimpse of what’s behind it. Security guards stand watch at an entrance gate and patrol the surrounding beaches on ATVs. Pickup trucks roll in and out, hauling building materials and transporting hundreds of workers.

Nobody working on this project is allowed to talk about what they’re building. Almost anyone who passes compound security—from carpenters to electricians to painters to security guards—is bound by a strict nondisclosure agreement, according to several workers involved in the project. And, they say, these agreements aren’t a formality. Multiple workers claim they saw or heard about colleagues removed from the project for posting about it on social media. Different construction crews within the site are assigned to separate projects and workers are forbidden from speaking with other crews about their work, sources say.

“It’s fight club. We don’t talk about fight club,” says David, one former contract employee. WIRED has agreed to withhold his real name because he was not authorized to speak to the press. “Anything posted from here, they get wind of it right away.”

Another former site worker, who we will call John, says he was told that another member of his construction company was fired for allegedly sharing a picture of the project on Snapchat. He’s heard similar stories from other crews. John says the “very strict” enforcement of NDAs has made workers on-site unwilling to “take the chance to get caught even taking a picture.”
