Here’s a short video of the Eiffel Tower flashing on the hour. I was taking the photo below when the Eiffel Tower started flashing. It actually surprised me even though I had been in the tower while it was flashing in the previous hour. I was inside on the second level getting a snack and studying a map trying to figure out where we’d go next when I noticed some flashing lights. It never dawned on me that the entire Eiffel Tower was flashing until I saw it again from below.
