Use of monitoring tools becomes more and more relevant at the increase of the ageing of heritage and historical infrastructures in order to properly drive the management and conservation procedures. In this framework; GPR method, and micro confocal Raman spectroscopy (CRS) methods were used in Keciova (Ketchaoua) Mosque (Casbah, Algeria) in order to visualize historical remains, foundations and basement infrastructures such as fractures, cavities or any other risk factors and identify minerals and rock types before restoration studies. The Mosque is an UNESCO World Heritage Site.
