Abstract
Introduction: The preservation of masonry buildings typical of Italian historical centres represents a very pressing dilemma founded on recovery need of the urban fabric original character. Methods: In the paper, based on a speedy methodology developed by some of the authors on building aggregates, the seismic vulnerability quick estimation of some masonry compounds in the heart of the town of San Potito Sannitico (Caserta, Italy) is presented and compared to the results achieved from applying the basic literature method for isolated constructions. Results and Conclusion: Finally, the damage scenario of inspected buildings has been shown by highlighting clearly the influence of different positions of structural units on the damages that masonry aggregates should suffer under different grade earthquakes, leading to individuate the most vulnerable buildings.

The preservation of masonry buildings typical of Italian historical centres represents a very pressing dilemma founded on recovery need of the urban fabric original character
The Italian historical centres are made up of masonry building aggregates characterised from an articulated genesis occurred during the centuries due to multiple factors, such as construction sequence, change of materials and variation of needs, as well as the relationship between the aggregation of building materials and both the morphological evolution of the urban system and the major events that have influenced the typological aspects of historical buildings
In the framework of a comprehensive study on the seismic risk of historical centres, large attention should be paid to the assessment of the vulnerability of constructions (V), of the seismic hazard (H) and of the exposure (E), the latter representing the number of assets exposed to risk
