Imagine a cave of nothing but celestine crystals. Pretty cool, right? In fact, Crystal Cave is the largest known geode in the whole world—and it’s hiding right here in the Buckeye State.

Why exactly is this natural wonder attached to a winery, you ask? Well, it all started in 1897 when workers discovered Crystal Cave while digging a well for the winery.
