Blue Hour Paris

Paris (ⁱ/ˈpærɨs/; French: [paʁi] ( listen)) is the capital and largest city of France. It is situated on the river Seine, in northern France, at the heart of the Île-de-France region (or Paris Region, French: Région parisienne). The city of Paris, within its administrative limits (the 20 arrondissements) largely unchanged since 1860, has an estimated population of 2,211,297 (January 2008), but the Paris metropolitan area has a population of 12,089,098 (January 2008), and is one of the most populated metropolitan areas in Europe. Paris was the largest city in the Western world for about 1,000 years, prior to the 19th century, and the largest in the entire world between the 16th and 19th centuries.

The blue hour comes from the French expression l'heure bleue, which refers to the period of twilight each morning and evening where there is neither full daylight nor complete darkness. The time is considered special because of the quality of the light at this time of day.
