Close to the town of Klevan in Ukraine there is a naturally formed 1.8 mile long tunnel. It grew around the path of a work train that made daily runs to a nearby factory. When the flora is in full bloom the tunnel is simply breathtaking, and romantic locals started calling it The Tunnel of Love.
Lore has it that the wishes made by lovers in the Tunnel of Love will come true if they are sincere in their love. And they probably all come true, because questioning the sincerity of the lovers that made their wish on the path of a multi-ton locomotive just seems inappropriate.
