Heritage buildings are considered among the most important landmarks of historical and human development in the city of Mansoura. In fact, the city includes many heritage buildings like Dar Ibn Luqman, Al-Shinawi Palace, the Great Mosque of Al-Salih Ayyub, Idris Mosque, and Al-Najjar Mosque, which have recently been subjected to many violations leading to the deterioration of their architectural form, as well as being affected by weathering factors, which is one of the most important damage factors that they face. This led to the spreading of many manifestations of damage such as peeling, efflorescence, disintegration, and disintegration. This study seeks to assess the geomorphological characteristics to better understand the heritage and archaeological place by identifying the historical origins of the monuments, showing their architectural style, analyzing them geographically, studying the geomorphological characteristics and conducting the necessary laboratory analyses. This research explores the most important issues facing archaeological and heritage monuments, such as changing climatic conditions including humidity, drought, and high ground water levels, in addition to wrong restoration processes, population overcrowding, and increased services within the city and the resulting urban sprawl around heritage buildings that made them more vulnerable to destruction and demolition, especially in the Mosques areas. What remains consequently is only a few scattered monuments that are not connected to the urban fabric. Therefore, the study offers a set of solutions to preserve heritage and archaeological monuments, protect them from degradation and destruction, work on their sustainability and benefit as well from them for future generations, and invest in them as culturally important tourist attractions of the city.
