The Bethesda Terrace, overlooking the Lake at Central Park, has two levels connected by a pair of grand staircases. There is also a third staircase that leads to a passage under the 72nd Street Cross Drive to the lower Terrace. While the staircase looks rather ordinary, the lower passage is absolutely astonishing. It makes you feel that you are in a secret underground chamber that may contain ancient artifacts and hidden treasures.
