The area of Montefeltro is predominantly mountainous and hilly, with wooded valleys interrupted by steep slopes. Due to its significant environmental, historical and cultural characteristics, Montefeltro is home to the Sasso Simone and Simoncello Regional Natural Park. Facing each other, for millions of years the great limestone boulders of Sasso Simone and Simoncello, together with Mount Carpegna with its 1415 metres, have been facing each other defining the horizon of the entire area. Their profile is unmistakable, and they have always been a fundamental reference point for those crossing this territory, imposing themselves on the view and exerting a great evocative power.
All around them are woods, meadows and rural environments dotted with castles, fortresses and villages that tell fascinating stories, as in the case of the fortress-city of Sasso, built by Cosimo I de' Medici around the middle of the 16th century. The most significant morphological element of the area is represented by the sharp contrast between the limestone outcrops, which form the main reliefs, and those with a prevalent clay component, which give rise to a gentle, hilly landscape. Urbino was one of the most important centres of the Italian Renaissance, whose architectural legacy it fully preserves. Its historic centre has been a UNESCO World Heritage Site since 1998.
