Thanks to all who guessed. ParisBreakfasts was the first to get it right. Now why does that not surprise me???? I was on top of La Samaritaine, on their rooftop cafe. What a view this was!!! Sadly, it is now closed. Reports have said it is a temporary closure, but many speculate that it will never reopen.
Interestingly, the name La Samaritaine comes from a hydraulic pump installed near the Pont Neuf(the nearest bridge crossing the Seine), which operated until 1813. There was a picture on the pump of The Good Samaritan…hence the name. The department store opened in 1869.
