The study has focused on structural conservation of a historical monument in an archeological site. Cevher Paşa Bath, which is located in Kale (ancient Tabae) archeological site in Denizli and dated to the 15th century, is selected as the case study. The aim of the study is to propose a framework for structural conservation of the ruins of Cevher Paşa Bath so that conservation work regarding similar masonry ruins in archeological sites belonging to Turkish period can be guided. First, the bath was documented by using 3D Laser Scanner. Then, historical and theoretical framework including development of baths, loads of masonry buildings and evaluation of interventions in similar cases was constituted. Characteristics of the case study was defined in terms of location, landform, history, site and mass characteristics, architectural features, structural characteristics, structural calculations and alteration analysis. Condition report of the bath was prepared in form of tables. To identify original state of the bath, restitution was carried out. Nevertheless, the restoration approach is not reintegration, but only consolidation and presentation in order to sustain integrity with the archaeological site whole. Therefore, to prevent further damages, emergency interventions such as temporary shoring are proposed. Structural calculations have revealed that strength of the walls corresponds to stresses and overturning moment. So, the restoration work includes only supporting of arch remains and the weakest corner of the bath, which was determined by calculations. Some walls of the ruin are weaker than other parts. These parts need further analysis by civil engineers, and if necessary, consolidation can be carried out. The monument management plan points out the necessity of collaboration of Kale Municipality, RT Ministry of Culture and Tourism, Aydın Regional Council for Conservation of Cultural Assets, Directorate of Excavations in General Directorate of Cultural Assets and Museums, Aydın Conservation Implementation and Inspection Office, Department of Architectural Restoration and Department of Civil Engineering of IZTECH and History of Art Department of Ege University, and monitoring of the changes the bath four times in every year.
