Megalithic architecture refers to ancient structures from the Eneolithic and Bronze Ages (5th–2nd millennium BC) that were built from large, uncut stone blocks without mortar.
These monuments represent some of the earliest examples of engineering and community organization, helping researchers understand how ancient societies lived, built, and interacted with their environment.
Documenting and analyzing megalithic architecture requires high accuracy, careful observation, and significant fieldwork. Modern technologies such as photogrammetry and 3D modeling greatly simplify this process while improving documentation quality.
Our Swiss partner Pix4D demonstrated these capabilities through the MEG-A (Megaliths of Akkar) project conducted by researchers and students from the Laboratory of Prehistoric Archaeology and Anthropology at the University of Geneva.

Project overview
- Location: Menjez village, Akkar region, Northern Lebanon.
- Site: A unique burial complex consisting of 45 megalithic tombs dating from the 5th–3rd millennia BC.
- Objective: Survey the interior of a megalithic tomb and accurately document its structure and archaeological contents.
Project challenges
Accurate documentation of archaeological sites located in remote or rugged landscapes presents numerous logistical and technical challenges.
Traditional survey methods using cameras, drones, and elevated platforms remain effective, but transporting bulky equipment across uneven basalt terrain is time-consuming and often impractical.
This becomes especially challenging when multiple archaeological sites must be documented within a limited field campaign.

Using PIX4Dcatch together with a standard smartphone provided a faster and more practical workflow while maintaining high survey accuracy.
Data collection methodology
After each excavation, researchers walked around the archaeological site while capturing photographs with an iPhone using PIX4Dcatch.
The application provided immediate visual feedback, allowing the team to verify complete site coverage before leaving the excavation area.
Combining careful excavation with photogrammetry enabled archaeologists to build a detailed digital database for every documented megalithic tomb.
During the project:
- 1,724 photographs were captured.
- Field data collection required approximately 30 minutes.
- Processing and exporting the final project required approximately 43 minutes.
Analysis of the resulting models revealed three distinct structural types among the documented tombs, providing new insights into ancient construction techniques.

3D documentation workflow
Using PIX4Dcatch, researchers quickly generated accurate three-dimensional models of the archaeological structures.
The resulting digital models were later used in Geneva to prepare:
- Cross-sections.
- Profiles.
- Sectional views.
- Detailed archaeological drawings.
- Digital documentation of the monuments.

Project benefits
- Fast on-site digital documentation.
- Immediate verification of image coverage during fieldwork.
- Reduced need for bulky surveying equipment.
- Accurate 3D models for post-processing and archaeological analysis.
- Support for creating orthophotos, profiles, cross-sections, and technical drawings.
- Efficient documentation of multiple archaeological sites during a single expedition.
Conclusion
PIX4Dcatch demonstrates how modern digital photogrammetry can significantly improve archaeological documentation by reducing fieldwork time while increasing the quality of recorded data.
Researchers receive accurate results directly on-site and can immediately determine whether additional photographs are required before leaving the excavation area.
This approach simplifies archaeological documentation, improves data quality, and supports the long-term preservation of cultural heritage through detailed digital records.
