Historical and cultural relics made of paper are among the most important artifacts of any culture and civilization and are valuable from a historical, artistic, scientific, economic, technical, and religious perspective. All paper materials change over time, so that this process cannot be completely stopped, but the speed of change can be controlled with conservation and restoration operations. The manuscript studied in this research is a manuscript document belonging to the year 1287 AH, and the Qajar period. The purpose of this research is to examine the used materials, pathology and finally to present a restoration plan for this manuscript. In this regard, after examining library resources, the fibers, glue, and materials used in the document were identified using laboratory studies, the type of ink used, and other tests for this document. Tests showed that the fibers of the document are wood and the sample contains a small amount of lignin, and the presence of starch and sugars was confirmed in the paste test. The acidity of the paper is 45.5 and the ink used in the document is of the metal-mazonite type and is sensitive to water. After completing the restoration stages of the document, the document was delivered to its owner.
The importance of the historical castles ofIlam province is above all because this region, as one of the government centers, was the site of the formation of prominent castles during the Sassanid period, which introduced the political and social structure of that era. Over time, a number of these monuments have lost their original function and have become abandoned, making their preservation an inevitable necessity. Adaptive reuse through appropriate change of use is an effective solution for the restoration of these valuable buildings. The main question of the research is: "How can we help preserve and restore the historical castles of Ilam with an adaptive reuse (AR) approach?" The research method is mixed and data were collected and analyzed from documentary studies and field observations. The statistical population includes ten students of the sixth semester of the Bachelor of Architecture program at Jundi- Shapur University of Technology in Dezful, and the "Architectural Design 3" workshop was chosen as the research context. The results show that the focus of the designs was on creating new spaces and the strategy of annexation was used more than installation and intervention. Also, the annexations were mainly formed in the form of two groups of space and element and the most extensive changes were in the facade materials. The final result indicates that the adaptive reuse approach not only helps to preserve and restore the historical castles of Ilam, but also, in the form of educational projects, improves students' understanding of how to integrate contemporary design with the historical and physical values of heritage buildings.
