Christmas is a very popular time of the year in most areas of the world, but especially in Europe. Although America has a higher percentage of Christians than France (63% compared to France's 50%) France is a much older nation and has had many more centuries than America to establish traditions like the Christmas Market. This means that these traditions are more meaningful to the general population, despite there being fewer actual Christians in the country. The Market has also become a positive event for the economy, bringing in money from tourists across the continent who want to shop at the markets. Because of this, France will likely continue this tradition for a long time.
The great majority of the Christmas Markets in France are outdoors, with the largest one in the Tuileries being in the gardens. When riding rides such as the Ferris Wheel or other tall attractions, people can see Paris from above, with the trees covering the gardens and the Eiffel Tower sparkling in the night sky. The cold weather also contributes to the tradition, as hot cider and hot chocolate are staple drinks to warm customers.
