The current paper presents all stages of a masonry building restoration including seismic per-formance assessment of the restored building, and a seismic retrofitting proposal accordingly. All these practices were carried out on a historical school building with timber slabs constructed in 1912. The study was composed of six stages: i. Historical research to identify all previous in-terventions in the building, ii. On-site examinations to determine the geometrical and structural properties of the building, iii. Laboratory tests to identify original material properties and determine repair materials, iv. Restoration decision and implementation of the restoration, v. Numerical analyses to assess the seismic performance of the restored building, and vi. Retrofitting proposal. The primary aim of this study is to present a comprehensive guide for seismic perfor-mance assessment and retrofitting approaches for similar buildings. The story shear forces and inter-story drifts of the examined building were obtained by linear and nonlinear analyses and compared with the limit values given in the applicable seismic code; accordingly, the seismic performance of the building was assessed. On the other hand, vertical and lateral bending collapse mechanisms were determined by local analyses. Based on the obtained findings, the building was found to have sufficient displacement capacity; however, failed in shear. Addi-tionally, we believe that the presented restoration practices and seismic performance assessment aiming the structural integrity of the historic building will contribute to the literature.
