This week, we take you to the Corinth Canal, the world’s deepest man-made waterway in Greece with walls soaring 79m tall and some areas as narrow as only 25m wide.

Engineering geologist, Haris Saraglou, inspects the canal to ensure it is stable for large ships like this 195m long cruise ship, the largest ship to ever attempt to cross the canal. Our unique aerial view allows us to witness this magnificent moment like you’ve never seen it before
