The castle with its four low, round towers or bastions, all in ruin, and surrounded by a moat, stands at the end of the city wall near the sea, and whatever strength it had was due to its environment; in spite of its situation it appears so insignificant that one wonders how, even in those days when the science of gunnery was in its infancy, it could have had any value as a fortress.
The Sforza palace is still standing on the little public square of which it occupies one whole side.

It is an attractive, but not imposing structure with two large courts.

The Della Rovere, successors of the Sforza in Pesaro, beautified it during the sixteenth century; they built the noble facade which rests upon a series of six round arches.

The Sforza arms have disappeared from the palace, but in many places over the portals and on the ceilings the inscription of Guidobaldus II, duke, and the Della Rovere arms may be seen.

Even in Lucretia's day the magnificent banquet hall--the most beautiful room in the palace--was in existence, and its size made it worthy of a great monarch.
