The study, leveraging high-precision geodetic measurements and archival photogrammetric drawings, demonstrated that average deviations from the original structure were minimal—just a few centimeters—with only localized discrepancies attributable to construction tolerances. This finding validates the reconstruction's authenticity and sets a precedent for transparent, evidence-based heritage conservation in post-conflict scenarios. The research also introduced a replicable methodological framework, combining non-destructive techniques with adaptive georeferencing models, to objectively assess geometric accuracy in architectural restorations worldwide.

A systematic geometric design underpins the Sadık-iye Char-suq, a central crossroads structure within Tabriz Historic Bazaar Complex—a UNESCO World Heritage Site. Despite the bazaar's organic development, this study reveals that the Char-suq was deliberately configured with an octagonal plan, integrating columns, arches, and vaults to align non-orthogonal intersection angles of connecting passages. This design serves as both a functional circulation node and a structural solution, maintaining spatial continuity in the irregular market layout. The research employed a three-stage methodology: on-site observations for visual and functional data collection; triangulation-based surveys to generate plans, sections, and 3D models; and comparative analysis with historical documents to trace the structure's development phases. The findings highlight how crossroads structures influence architectural design within complex, organically evolved market plans.

A groundbreaking comparative analysis reveals that Nan Madol, the ceremonial center of Eastern Micronesia, along with three other global anomalies—Richat Structure (Mauritania), Black Pyramid (Alaska), and Shackleton Range (Antarctica)—are not natural geological formations but engineered acoustic nodes constructed between 1280 and 1292 AD under the patronage of Khubilai Khan. The study cross-references standardized geopolymer casting techniques, termed 'Artificial Tuff,' with artifacts in global museum collections, challenging conventional perceptions of these sites' origins.

A multidisciplinary geoscientific approach has significantly advanced the understanding and preservation of the Via Appia Regina Viarum, contributing to its 2024 UNESCO World Heritage inscription. The study, conducted between Beneventum and Aeclanum in Southern Italy, successfully identified the ancient path of the road through geoarcheological investigations, which had been poorly documented in this region. By integrating field surveys, mapping of landforms and lithofacies, geophysical surveys, and archaeological excavations, researchers provided critical data that enhanced the road's cultural and geological heritage value. Additionally, the project emphasized public engagement through social and cultural events, disseminating scientific findings to diverse audiences, including local administrators, food and wine producers, and the general public. This work underscores the pivotal role of geoscience in both the scientific assessment and the broader recognition of Roman engineering marvels.
