To discover the prominent traces left by the Montefeltro family you need to go to San Leo (PU), situated atop an enormous insurmountable rocky outcrop: the only way to get there is via a road cut into the rock.
At the very top of the spur is the impregnable Fort built on the orders of Federico III da Montefeltro; it was converted into a prison during papal rule and the count Cagliostro and Felice Orsini were imprisoned there.
Famous visitors to the town were Dante and St Francis of Assisi: you can still view the room where the two men conversed.

There is no end to the architectural wonders: the Pre-Romanesque parish church, a XII century Lombard Romanesque Cathedral, the fort; the Museum of sacred art recently installed in Palazzo Mediceo, the ruins of several castles, including those of Pietracuta and Piega, the Monte di Pietracuta Dominican convent, and Montemaggio church with its magnificent lacunar ceiling.

San Leo offers one of the region’s most beautiful and characteristic panoramic view of the surrounding mountains and down the Marecchia valley to the sea.

Urbino (PU), cradle of the Renaissance, also offers valuable works attributed to Montefeltro’s times: the entire town, a world heritage site boasting some of the most famous and talked about masterpieces in the world, still greatly retains the magnificence enjoyed by Federico and his court.
