Although much of Pompeii Âremains in good repair, the problems are numerous, including “inappropriate restoration Âmethods and a general lack of qualified staff… restoration projects are outsourced and the quality of the work of the contractors is not being assessed. An efficient drainage system is lacking, Âleading to water infiltration and excessive moisture that gradually degrades the structural condition of the buildings as well as their decor. The mission was also concerned by the amount of plant growth, particularly ivy.”
