Abstract: The archaeological site of Santa Maria's Sé-Cathedral is located in the parish of Idanha-a- Velha (Portugal). Roman municipium in High Imperial Era, when structures dated to the First and Second Centuries AD are documented, it appears that this city was known as Ciuitas Igaeditanorum and developed a reputation along the Fourth Century AD. as a new Episcopal See. In this moment a Christian cult building was erected from another one in an earlier structure. This last building persists even in Islamic Period, at the same time that another new Mozarabic structure that was added to the complex at the end of the Ninth Century. Given the presence of numerous phases of occupation and therefore, a several techniques and materials construction, archaeological direction decided to analyze some constructive elements like mortars present in joints, coatings and plasters of different rooms. Different macroscopic techniques were developed using high resolution images taken from, combined with the use of software that analyze the data obtained from colorimetries test and the spectral analysis from the mortars cross sections. Relevant results have been obtained in relation to the quantitative characterization and the composition of each mortar.
