Pedaso is a comune (municipality) in the Province of Fermo in the Italian region Marche, located about 60 kilometres (37 mi) southeast of Ancona and about 35 kilometres (22 mi) northeast of Ascoli Piceno.
Moresco means literary “Moorish”. According to legend, at the time of their raids along the Adriatic coast, a group of Moors went further into the interior in order to build a fortress in the heart of Christianity. Others, on the contrary, maintain that the Castrum Morisci was built near the sea to drive back the assaults of the Saracens. Most probably the place name comes either from a noble family named Mori, or from the word in dialect morrecine, which refers to the heap of stones on which the castle rests.
