The process was rather quick once the castle, as a distinct type of fortress, was introduced. However, it took different forms in different lands. The methods and reasons of encastellation differed based on law (who could legally build a castle), necessity (who needed a castle), and geography (where could castles be effectively built). The stone castle originated probably in the north of

Italy
In Italy, the process of encastellation is known as ''incastellamento''. It has a specific notion, as the ''incastellamento'' describes less the building of castles than the change towards fortified settlements, in which the castle proper (''rocca'') is a separate part. The term 'incastellamento' for this process was coined by
Pierre Toubert. As in France, it was a different process in the north and the south.
In the north, the castles were originally the seats of the barons. They spread quickly after the disruption of royal authority in Italy in the mid-tenth century. By the eleventh century, the territorial magnates, like the

Loud considers ''incastellamento'' as one of the chief reasons for the decline in princely influence in Benevento and Capua (especially the former) during the late tenth century.
