This study aims to rehabilitate Hammam al-Sarah, a unique bath complex located in the northeast of Jordan, built in the first half of the eighthcentury. The importance of this article stems from the fact that all studies conducted so far were limited to the description of the monument ignoring the intrinsic value of its restoration. In this research, the authors visited the monument to investigate the constructional techniques and materials used in the building. The study team explored the procedures to restore the building and present it to the visitors. To that end, stone and mortar samples were analyzed in order to preserve the monument and its cultural values. The analyses used in this study provide guidelines for the conservation of this neglected monument. Results show that it is extremely important to use materials, i.e., stones and mortar similar to those used in the original building.
