Mapping building materials and alteration forms to diagnosis, conservation and restore: a Norman castle in Sicily

Abstract

In this short paper we present the results of a diagnostic study performed on building materials of the Adrano Castle in Sicily, part of a system of watchtowers extending around the Etna Mountain. Stone materials, plasters and mortars have been studied from macroscopic point of view to produce maps of the Castle façades. The results of this study provided a fundamental contribute to the reconstruction of architectural phases interesting the Castle and the definition of relative chronology based on microstratigraphic data, greatly supporting also the restoration works in selecting compatible replace materials.
