In the arid wastes of eastern Yemen lies a fascinating natural wonder called the Well of Barhout. Shrouded in mystery and folklore, this large hole in the ground said to be the most hated spot on Earth to God.
Located in the eponymous valley, Barhout Well is 30 meters wide and thought to be anywhere between 100 and 250 meters deep. The depth is just pure estimation, as no one has been down to the bottom of it, and considering the chilling legends and stories surrounding it, I doubt any of the locals would attempt a decent. Not even Yemeni scientists and explorers have been able to reach the bottom, as the low oxygen and strange odors emanating from the well forced them back to the surface.
