Paris is the capital city of France. It is situated on the River Seine, in northern France, at the heart of the Île-de-France region ("Région parisienne"). Paris' location at a crossroads between land and river trade routes in lands of abundant agriculture had made it one of France's principal cities by the 10th century, rich with royal palaces, wealthy abbeys and a cathedral; by the 12th century Paris had become one of Europe's foremost centres of learning and the arts. Today, Paris is a major influence in politics, fashion, business, arts and science. The city serves as an important hub of intercontinental transportation and is home to universities, sport events, opera companies and museums of international renown, making it an attraction for over 30 million foreign visitors per year.
