In addition to recent conflict and disasters, two topical events have stressed the critical need for digital heritage documentation: the devastating fire at Notre-Dame de Paris, France, in 2019 and the colossal explosion in 2020 at Beirut port, Lebanon, which caused extensive damage to a huge number of, mainly historical buildings. The former was well documented by various digital techniques which facilitated the restoration and preservation of the iconic monument [1, 2], while the latter was not fully documented, which makes preserving the damaged heritage more challenging.
This website is one of the outcomes of the University of Liverpool Fellowship in Heritage 2021. I would like to thank my mentors from University of Liverpool (UK):
Dr. Ataa Alsalloum &
Dr. Nicholas Webb
Also I would like to thank Beirut Arab University (Lebanon):

Prof. Ibtihal Youssef El Bastawissi, Dean Faculty of Architecture - Design & Built Environment for their support.
All the case studies are located in the historic part of Tripoli City at the north of Lebanon (see the map) except the last two cases. They are located in historic Cairo for the purpose of comparing between some cases in Tripoli and Cairo.

Process used in affordable photogrammetry
The photogrammetry outcome is used to extract real dimensions; 2D orthogonal drawings from plans, sections, and details; in addition to diagrammatic dross-sections to understand the building's form. Affordable tools used are mobile camera, and Metashap Agisoft educational software version.
