In this study, a numerical model was developed to assess the settlement and the damaging mechanism of an old masonry church Adormirea Maicii Domnului located in Perisoru village, Romania by using finite element software Plaxis 3D. The main aim of this research was to simulate the ground problems and the structural failures observed. The rectangular foundation is placed on yellowish silty clay-loess, which was modelled and analysed in the present paper. Mohr-Coulomb soil model was used for the soil and the linear elastic model was used for the foundation. After computing the settlements, it was resulted the need of improving the soil. The soil was improved with cement, but some nano materials were considered as well, as an alternative. The results showed that the value of the settlements reduced with an increase in the amount (0.5%, 0.75%, 1%, 2%) of the Nano-MgO. The results have been compared with the soil treated with 2 % cement.
