This work deals to determine the physical and the mechanical properties of the granitic rocks used in the Roman amphitheatre in Emerita Augusta. For this purpose, petrographic, geochemical and physical and mechanical analyses were used. The sampling in the amphitheatre was carried out taking into account granitic rocks that have not been replaced during its numerous restoration works. Mineralogical, textural, geochemical, physical and mechanical properties of the granitic rocks were obtained trying to obtain the relationships between them and showing that porosity influences in their mechanical properties. The petrographic characterisation and the geochemical signature of the samples allowed us identifying the granite types used in the monument as well as the acceptable conservation state of it.
