ALEPPO - BEFORE AND AFTER

Abstract. In October 2018 I was in Aleppo, Syria, for my second time after the visit in 2010 before the war. It was an unique opportunity to perform 3D surveys of some noticeable buildings and monuments affected by the war. The paper shows some 3D results and comparisons for same monuments. The objects of the survey are some parts of the Citadel walls, the entrance tower of the Citadel, the southern tower, one mosque, the minaret of the Citadel mosque. These results prove undoubtedly that photogrammetry is an essential instrument for the 3D documentation and digital preservation of cultural heritage. The used technique is spherical photogrammetry, based on panoramic images and ad-hoc processing processes. The technique is very much suitable for heritage documentation and if will be transferred to the students of the local faculty of architecture.
