The Eiffel tower is one of the worlds most iconic landmarks and is without a doubt one of the most photographed structures by tourists, but why all the fuss about photos taken at night being illegal?
As it stands, the European Union's Copyright law dictates that the original creator holds the copyright for his/her entire life plus 70 years thereafter before it comes public domain. The Eiffel Tower, however, was constructed in early 1887 and the original designer, Gustave Eiffel, passed away in 1923 which means that the copyright has officially ended, so therefore anyone can take photos of the Eiffel tower for commercial purposes without any consequences.
However, the lights on the Eiffel Tower were not installed until 1985 which reinstated a copyright to the designer and installer Pierre Bideau which means that any photo or video that contains the Eiffel Tower with its lights on is a violation of copyright law. For private use, it's not an issue, but don't try and sell your photos on a stock library or you might get into some trouble.
