There are many historical buildings, religious monuments and ruins of ancient civilisations. The Naziresha Mosque in Elbasan, is one of the few Ottoman mosques still functional in Albania and the only preserved mosque of the city. It was built during 1590s. It has a square plan and only one cubic shaped central hall. The transition from the cube to the dome is provided by pendentives. This unique structure’s current condition is alarming mostly due to lack of concern. Frequent Seismic activity, amortization, aging and non-proper maintenance have leaded the mosque towards degradation. In this paper, assessment of current structural conditions is carried out. A FEM analysis is applied to examine at what extent the structural defects endanger the stability of the mosque. As a result, solutions for the structural problems and enhancing the existing structural capability are suggested. The strengthening techniques are proposed, taking into consideration preservation of the cultural, historical and architectural values of the mosque.
