The most recent population dynamics within Italy and, more generally speaking, the processes of spatial reorganisation that have been taking place for several decades in this country as well as elsewhere, have coused major transformations in the settlement system of the Italian Alps. Twenty years on, it seemed logical, then, to continue the research already existing on the region's urban network. Given the need for a new picture of the settlement order of the Alpine arc, the main aims of this work are to update existing studies, with particular attention to the classification of the towns into the principal typologies of funcional size (cities, medium-sized towns and small towns) and to attempt to identify the emergence of new nodes within this area, which is currently undergoing reterritorialisation on various scales.
