It is true everything about her in Pesaro was small when compared with the greatness of Rome, but here she was removed from the direct influence of her father and brother, from whom she was separated by the Apennines and a distance which, in that age, was great.
The city of Pesaro, which now has more than twelve thousand, and with its adjacent territory over twenty thousand inhabitants had then about half as many.

It had streets and squares with substantial specimens of Gothic architecture, interspersed, however, even then, with numerous palaces in the style of the Renaissance.

A number of cloisters and churches, whose ancient portals are still preserved, such as S.
Domenico, S.Francesco, S.Agostino, and S.Giovanni, rendered the city imposing if not beautiful.
Pesaro's most important structures were the monuments of the ruling dynasty, the stronghold on the seashore and the palace facing the public square.

The last was begun by Costanzo Sforza in 1474 and was completed by his son Giovanni.

Even to-day his name may be seen on the marble tablet over the entrance.
