Public lighting plays a fundamental role in modern cities and has evolved considerably throughout history. In Ancient Greece and Rome, rudimentary methods such as torches and oil lamps illuminated some streets. During the Middle Ages, castles and European city streets used oil lanterns and, later, candles. A significant breakthrough came with the invention of the gas lamp in the late 18th century, first used for public lighting in London in 1807, which improved street visibility and helped reduce crime. Thomas Edison’s invention of the electric lamp in 1879 revolutionized public lighting, and incandescent lamps began replacing gas, providing more efficient and safer illumination.
