When did tourism first start in Paris?

Tourism in Paris can be traced back to the 18th century. At that time, wealthy British aristocrats began to travel to Paris on the "Grand Tour" of Europe. They were drawn to the city's art, architecture, and culture. In the 19th century, tourism in Paris increased dramatically thanks to the development of the railway system. This allowed more people to travel to the city, and it became a popular destination for both domestic and international tourists.
