* Gas Lighting: In the 19th century, Paris was one of the first cities to adopt gas lighting on a large scale. This replaced the dim oil lamps and candles of the time, creating a much brighter and more modern urban landscape. The city became known for its illuminated streets and buildings, earning the nickname "City of Lights".
* Cultural Significance: The term "City of Lights" also reflects Paris's status as a center of culture, art, and intellectual life. It was seen as a beacon of enlightenment and progress, drawing people from all over the world who sought knowledge and inspiration.
While the gas lighting is no longer the primary source of illumination, the name "City of Lights" has stuck. It evokes the city's history of innovation, its vibrant cultural scene, and its enduring appeal as a destination for beauty and excitement.
