This study present different photogrammetric techniques to document the original situation of damaged or destroyed heritage monuments in three-dimensional digital form. The first part describes the reconstruction method integrating Spherical photogrammetry and dense matching, two interesting 3D reconstruction techniques. They are both used in architectural heritage applications. The second part of the article discusses the representation of the model and its accuracy, since it is almost impossible to have the same quality for an entire monument, overall when it is photogrammetric reconstruction with limited image resources. The workflow was applied to the Arch of Triumph which was destroyed by the so called "Islamic state" in September 2015. The photogrammetric reconstruction made use of touristic images collected from the web and panoramic professional images captured before the destruction of the monument. The relative accuracy is discussed and how the integration of the two photogrammetric techniques could be useful to obtain almost complete 3D model and explaining the used workflow to reach a worthy representation of the monuments.
