The Natural Park of the Sasso Simone e Simoncello, established in 1994, occupies a surface of 4.847 hectares in the province of Pesaro-Urbino and Rimini, including the old territory of Montefeltro. The landscape of hill and mountains has two principal mountains: Monte Carpegna to North-east, summit of the park and watershed between Foglia valley and Marecchia Valley; Sasso Simone e Simoncello to the south-west. The park is set in the towns of Carpegna, Frontino, Montecopiolo, Pandimeleto, Pennabilli and Pietrarubbia. This landscape is characterized by geomorphological and naturalistic elements full of historical values. The green heart of this park hides the history of the “Città del Sasso”, founded by Cosmo I dei Medici in the middle of the XVI century.
