LAYERS project – preliminary results from GPR and ERT surveys at Museu do Azulejo

Abstract

LAYERS research project* proposes to explore, using geophysical methods, such as ground penetrating radar (GPR) and electrical resistivity, in the thickness of the walls and in the soil depth around buildings of heritage interest, and the layers in which the history of constructive and decorative elements, such as azulejos, may be revealed. In this paper, the results of some GPR and electrical resistivity tomography profiles carried out at Museu do Azulejo are presented. Preliminary results point to the identification of tombstones thickness, pathway detection of water supply system between two cloisters, and the possible presence of an underground water tank.
