 Rimini is located in a historically strategic position, at the extreme southern edge of the Po Valley, at the junction point of Northern and Central Italy.It is surrounded towards southwest by the gently rolling hills of Covignano (153 metres high), Vergiano (81 m), San Martino Monte l'Abbate (57 m) and San Lorenzo in Correggiano (60 m), widely cultivated, with vineyards, olive groves and orchards, and dominated by ancient mansions.These hills, mostly made of clay and sand, connect the plains, created by the Marecchia and Ausa, the two most important rivers of Rimini territory, to the higher hills of the Apennines.
