BENEATH THE HAGIA SOPHIA - The Secret of the Wells 

“This is a preview film about the mystery of the wells explained in the documentary. Until the Beneath the Hagia Sophia documentary was filmed, no one had entered the wells, no one had taken their measurements. How they became wells, how deep they reached, whether they were connected to each other was unknown. More importantly, what was at the bottom of these wells? Even if the preview film does not answer these questions, it offers clues for the viewers.”
