Abstract. The paper explores the possibilities of using old images for 2D and 3D documentation of archaeological monuments using open source, free and commercial photogrammetric software. The available images represent the external façade of the Western gate and Al Omari Mosque in the city of Bosra al-Sham in Syria, which were severely damaged during the recent war. The images were captured using consumer camera and they were originally used to achieve 2D documentation for each part of the gate separately. 2D control points were used to scale the digital photomosaic and reference distances were applied for the scaling of the 3D models. Archive images were used to produce a 2D digital photomosaic of the monument by image rectification and 3D dense point clouds by applying Structure from Motion (SfM) techniques. The geometric accuracy of the results has been assessed.
