Tours, where the University of Francois Rabelais is located, is the center of central France, the largest city there and one of the important economic centers on the main traffic axis in Europe. It takes only 55 minutes to get to Paris by TGV. Since the opening of the railway line through Paris Charles de Gaulle International Airport (1 hour 45 minutes), Tours has shouldered a veritable international mission. In addition, Tours also benefits from its unique geographical location in the center of the Royal River Castle District: the Royal River Castle Group has a long history and is listed as a human cultural heritage by UNESCO. La Dulan is also the hometown of many famous French writers, such as rabelais, Lansard and Balzac.
