You are in Paris, also known as the City of Light, right? So, it comes as no surprise that an impressive number of monuments and buildings in the city are illuminated to full glory every night. If you want to see one of the world’s most recognisable landmarks, the glittering Eiffel Tower for free, head to Trocadéro Square when the night falls. Although climbing the monument itself will cost a pretty penny, you can capture gorgeous Instagram photos and take in one of the most stupendous views of the beautifully illuminated Eiffel Tower from the square. Just sit on the wall going down the stairs to enjoy the amazing light show every hour for free.
