Japan might be the land of cherry blossoms, neon cities, and serene temples—but tucked away between the islands of Shikoku and Awaji lies one of its most mysterious natural wonders: the Naruto Whirlpools. These aren’t just cute little eddies. We’re talking about giant oceanic whirlpools, some as wide as 20 meters, forming like clockwork beneath the dramatic span of the Ōnaruto Bridge.

Imagine living in a castle that has survived wars, fire, and centuries of change — and still holds royal banquets today. Welcome to Windsor Castle, not just the oldest but also the largest occupied castle in the world. This isn’t a relic frozen in time; it’s a royal residence, a fortress, a chapel, and a living museum all wrapped into one stone-clad wonder.
