Realisation of provisional works for the securing of the Porta dei Mariani and the Porta dei Vettori

The general conservation status was within the parameters of the works located in an external environment. Regarding the brick elements, a general situation of surface pulverisation and limited areas (where acid attacks have more significantly affected the conservation of individual elements) had been detected. The pietra serena constituent the blocks of the entrance arch had the typical pathologies of this lithotype, such as exfoliations and pulverisation of exposed surfaces. The major alterations were, however, related to the considerable extent of biodeteriogenes on all the materials constituting the surfaces of the manufacture.
