 Tourism in Rimini started as therapeutic stay (thalassotherapy, hydrotherapy and heliotherapy), evolving into elite vacation in the late 19th century, into middle-class tourism during the fascist era and finally into mass tourism in the postwar period.On summer nights, there is a festival called "La Notte Rosa".Rimini concentrates a quarter of Emilia-Romagna's hotels, with over 1,000 hotels, 300 of which are open all year round, and hundreds of apartment hotels, apartments, holiday homes, bed & breakfast and campings.
