Imitation of stone stereotomy with protruding joints, a decorative technique which consisted of applying a wall revetment that simulates cut stone in order to disguise the true nature of a structure consisting of poorer materials, was also used in the Algarve region. In total, it was possible to identify traces of the application of this unusual technique in at least five religious buildings of the Algarve region built or subject to major campaigns of works between the fifteenth and sixteenth centuries.
