Panorama of Paris, France showing the Seine, seven bridges and the Eiffel Tower. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light" both because of its leading role during the Age of Enlightenment and more literally because Paris was one of the first large European cities to use gas street lighting on a grand scale on its boulevards and monuments. Gas lights were installed on the Place du Carrousel, Rue de Rivoli and Place Vendome in 1829. By 1857, the Grand boulevards were lit. By the 1860s, the boulevards and streets of Paris were illuminated by 56,000 gas lamps. Fair to good contrast and tonality. 8.125 x 10.75 in. 21 x 27.5 cm. Rev: A view of the Tuileries Palace, Paris. was a royal and imperial palace in Paris which stood on the right bank of the River Seine, directly in front of the Louvre. It was the usual Parisian residence of most French monarchs, from Henry IV to Napoleon III, until it was burned by the Paris Commune in 1871. Built in 1564, it was gradually extended until it closed off the western end of the Louvre courtyard and displayed an immense façade of 266 metres. Since the destruction of the Tuileries, the Louvre courtyard has remained open and the site is now the location of the eastern end of the Tuileries Garden, forming an elevated terrace between the Place du Carrousel and the gardens proper.
