City of Light: A culture lover's guide to Paris

Art Nouveau buildings in Paris.
Paris was named the City of Light at the beginning of the 19th century due to it being the first European city to use gas to power its street lighting.Â
It is an apt moniker for the illuminated views across the city at nighttime, especially from the SacrĂ©-Coeur Basilica in Montmartre.Â
