Abstract
In the context of the current scientific collaboration between the Soprintendenza per i Beni Archeologici di Roma and the Laboratorio di Sperimentazione Mineraria e Petrografica del Ministero dello Sviluppo Economico, a study has been carried out on some tuff blocks recovered during the redecoration of the historic building where our laboratory is located (the building is on Quirinale hill). Archaeological sources affirm that these blocks belong to the first wall that surrounded Rome, the wall named “Mura Serviane”. It was built from the 6th to the 4th century B.C. An archaeometric study of the tuff blocks has been carried out aiming to identify the kind of raw materials used and to compare the results with the data regarding the tuff banks set in the area of Rome: in the central area and in the north of Rome.
