The Eiffel Tower's likeness had long since been part of the public domain, when in 2003, it was abruptly repossessed by the city of Paris. That's the year that the SNTE, the company charged with maintaining the tower, adorned it with a distinctive lighting display, copyrighted the design, and in one feel swoop, reclaimed the nighttime image and likeness of the most popular monument on earth. In short: they changed the actual likeness of the tower, and then copyrighted that.

As a result, it's no longer legal to publish current photographs of the Eiffel Tower at night without permission.
