The old heritage of Alhadba Minaret in Mosul is famous for its considerable height and leaning. After approximately 800 years since its construction still withstanding degradation. It has to be clearly documented for restoration and maintenance works. Defining geometry and measurements using traditional surveying methods is not feasible due to its height and delicate surface. This paper introduces the results of measurements using robotic reflectorless total station of TOPCON (IS-Imaging Station) conducted in and around the minaret. We present new facts regarding the descriptions of shape and curvature of the minaret body as well as specific notes on using this instrument. These measurements compose a complementary part of data collection effort required for a major preservation project that is proposed to be conducted in the future.
