Just outside the city of Klevan in the Rivne oblast in Western Ukraine, a nearly two-mile stretch of private railway has turned the surrounding trees into an enchanting natural tunnel. It’s called the Tunnel of Love. Back in the Cold War era, the railroad led to a secret military base, and the trees were deliberately planted alongside the track to conceal the transport of military hardware. The moving trains have formed the branches of the trees into a shape resembling the tunnel. As can be seen, it is beautiful in any season of the year and is a place of attraction for people around the world.
