In the context of increasing demand for advanced digital heritage preservation methods, the current state of the art is dominated by terrestrial laser scanning, mobile mapping systems, and photogrammetric techniques, which have proven highly efficient in generating precise 3D datasets for complex structures. This paper aims to explore and evaluate modern technologies used for the three-dimensional documentation of the historical monument Brück Castle, a monument of significant cultural and architectural value for Timişoara municipality. For this study, data acquisition was performed using a terrestrial laser scanner and a mobile mapping system. Georeferencing was ensured through the integration of a total station and a GNSS receiver. The acquired data were processed and analyzed using two different software, which allowed a precise point cloud registration, filtering, and visualization. The novelty of this research lies in the combined use of both terrestrial and mobile laser scanning for documenting the same historic building, enabling the evaluation of accuracy, efficiency, and complementarity between the two approaches. The results demonstrated a high level of geometric fidelity in the final 3D model, with deviations within acceptable tolerances for heritage documentation. However, some limitations were identified, such as restricted accessibility to certain building areas and the influence of environmental conditions on data acquisition. Despite these constraints, the study highlights the relevance of integrating multiple surveying technologies for heritage preservation. The originality and significance of this work stem from its contribution to the methodological framework for documenting historic architecture, providing a replicable workflow for future research and conservation projects.
