• Assuming that the churches belonging to each of the two groups (Italian churches and Romanian churches) have very similar characteristics and are located in neighboring geographic areas, the methodology at the wide area level does not allow for significant differentiation of the sample from a class evaluation, rather from a score assessment. • The next levels of assessment are needed to provide more refined classifications.

5. Conclusion and future steps This paper reports preliminary results of a new proposed multilevel and multicriteria methodology for the risk assessment of existing masonry churches. Firstly, the frameworks present in literature are summarily reported and compared, since they are all considered for the conceived procedure. Then the new methodology is briefly described and levels of assessment characterized. For this work only the wide area level of valuation is applied ( Level 0_E ), by investigating churches located in two different countries in Europe (Italy and Romania) but presenting similar characteristics and located in neighboring areas if considered in the same group. Next, case studies are presented and involved in the methodology. Finally, the results obtained from this first level of analysis are discussed and some observations made. The research will proceed by developing the next levels and by applying them to the same church sample or to a larger one.
