Built back in the 10th century, the incredible well of Chand Baori, India was a practical solution to the water problem in the area. The arid climate forced the locals to dig deep for a dependable water source, one that would last throughout an entire year. Chand Baori well is 30 meters deep, it has 13 floors and 3,500 steps. Legends say that ghosts build it in one night and that it has so many steps to make it impossible for someone to retrieve a coin once it’s been dropped in the well.
