<p>The management of cultural landscapes, which encompasses historic buildings and archaeological heritage, faces complex challenges due to the unique nature of these structures and their vastness. An innovative approach to addressing these challenges involves integrating semantically enriched 3D modeling, such as Historic Building Information Modeling (HBIM), with Historical Geographic Information Systems (HGIS). This integration allows for a comprehensive understanding of historical structures at different scales and levels of knowledge, from individual components to territorial contexts and their history. We conducted an innovative study based on the application of HBIM-HGIS for multi-scale digital documentation of architectural heritage, focusing on archaeological heritage, such as the former 20th-century prisons located on Anchieta Island, São Paulo, Brazil. We proceeded in two stages. In the first stage, we collected, georeferenced, and vectorized historical data, adding descriptive information. In the second stage, we modeled the structures in detailed three-dimensional using terrestrial and aerial scanning techniques, integrated HBIM data into a geographic database, and created a 3D WebGIS for data visualization and management. The results demonstrated significant innovation in HBIM-HGIS integration, providing deeper understanding and precise analysis to support the preservation of historical complexes and cultural landscapes. Our approach contributes to more effective and comprehensive management of cultural heritage at various scales, from landscapes to specific details of historic buildings.</p>
