IThe historical heritage is characterized by the presence of some peculiarities that make them unique. These peculiarities represent the material evidence both of the local building history both of the cultures that created them. Due to its characteristics and peculiarities, the historical heritage that defines the monumental and minor buildings of Italian territory must be protected and enhanced. However, its intrinsic vulnerability and fragility makes these objectives particularly complex to be achieved in highly seismic territories such as Italy. This is also highlighted by the seismic events that have occurred in the last decade causing considerable and inestimable damage to building heritage locate in historical urban areas. The earthquake that struck Abruzzo region in 2009 affected the building heritage of L’Aquila and other 56 minor historical centres, which are characterized by the presence of a stone masonry buildings that have some characteristics of great value. Therefore, in the reconstruction process historical centres damaged by the earthquake to recover the peculiarities of the building fabric a parametric model (IMC model) has been implemented to define the allowable grant to carry out the repair and strengthening works of the damages. In the IMC model some valuable elements, related to architecture, materials and territorial construction techniques, have been identified in order to enhance and preserve the historical character. To these valuable elements are assigned 15 grant increments, that allow to increase the conventional cost in order to promote interventions aimed at conservation and to cover the higher costs expected. Starting from this brief summary, this paper deals with the issue of the reconstruction of minor historical urban areas, describing the interventions planned for the conservation of local specificities and identities according to the common conservation guidelines.
