D'Ammaedara a Haidra takes readers on a journey through the different periods of Tunisian history, from antiquity to the present day, via the medieval and modern periods. Haidra, a small town located on the western border between Tunisia and Algeria, is the setting for this exploration. This study is an experiment linking history and architectural archaeology, with the aim of highlighting fragments of history, events, figures and the little-known heritage of this town and its region. Based on archival documents, various sources and existing studies, the book addresses issues related to the occupation of the site from Antiquity to modern times, taking into account the regional, tribal, socio-economic and security context, with particular attention paid to the ancient site. After extensive fieldwork, an archaeological and architectural analysis was carried out using various methods of building archaeology, focusing on construction techniques and materials, and culminating in an attempt at restoration. These two approaches, historical and architectural, have contributed to a comprehensive understanding of Haidra and its occupation over time.
