The pavilion with columbaria and chapels of the Leffe cemetery was built in the early 1930s, on a design by the engineer Giulio Fossati. The project draws on a belated historicist language, and in particular on the neo-Egyptian taste, quite widespread in cemetery architecture between the nineteenth and twentieth centuries, yet quite unusual in the area. The whole architectural apparatus is made of artificial stone, namely white and dark gray conglomerates, plausibly made with natural cement: elements that show severe forms of decay due to the usual actions of atmospheric agents, worsened by the widespread corrosion of the interior rebars and the consequent cracking and detachment of the material. Starting from the reconstruction of the building events and an accurate material and decay survey, the executive project focused on the adjusting of the roofing and the securing and restoration of the artificial stone apparatus.
