There are a few castles in Northern Uzbekistan that are constructed from untreated earth material. One of the most famous ones is the Toprak Qala near Urgench, Uzbekistan. It is dated to be from the 2nd – 3rd centuries and used to be one of the forts on the northern branch of the Great Silk Road, a trading route between Europe and China. It is located right at the edge of the Kyzyl-Kum Desert. Since it is constructed from untreated earth material, it has deteriorated over time. This process was accelerated by the failure of the original drainage system, which caused rainwater to remain trapped inside the monument. The main objective of this paper is to evaluate its current condition and identify the “hot” spots of the monument which require immediate attention. The objective is achieved by conducting a laser scanning expedition to capture the monument’s current condition by means of a terrestrial laser scanner. The monument was scanned from more than 20 different stations. All of them were stitched into a single point cloud that reflects its current condition in a 3D rendering with a few millimeters accuracy. Essentially, a digital twin of the current state of the monument was created. The laser scanning was conducted in the summer of 2022. A follow-up expedition is scheduled for the summer of 2023 to quantify the rate of deterioration over one year. This paper provides examples of detailed analysis of the current condition, the results of which will be utilized in future comparative studies of two laser scans separated by a year. A summary of the major findings of the project is provided.
