Mark Zuckerberg's Massive Underground Bunker at Koolau Ranch

planned

Mark Zuckerberg is building a self-sufficient, massive doomsday bunker underneath his Koolau Ranch property in Hawaii. The project includes multiple mansions, an entire village, and a 5,000-square-foot underground bunker with reinforced concrete and metal doors for protection against radiation. The compound spans 110 acres and features self-sustaining facilities such as a water reservoir, pumping system, farming, livestock, guest housing, gym, sauna, swimming pools, tennis court, and treehouses connected by rope bridges.
