Sicily and Malta, with their architectural and artistic heritages and close geographical proximity, share commonalities that can benefit both in the socio-economic sphere.

The architecture on the two islands is often very much alike because the same architects and artisans traveled around the Mediterranean and disseminated their knowledge. Construction techniques are similar too, including the use of stereotomy, a centuries-old science that uses complex geometric knowledge to cut blocks of stone and resolve complicated structural solutions. An in-depth study of this field, as LITHOS proposes to do, can provide important clues in the rediscovery of ancient traditions, which can then be applied both to new construction and to the restoration of stone facades in the historic towns and sites of Sicily and Malta.
