A Bird’s-Eye View: Drone Surveys with Arabian Space Imaging
Looking at Hegra’s tombs from the ground is always awe-inspiring, but seeing them from above? That’s a whole different experience. This month, we had the incredible opportunity to gain a new perspective on the site by teaming up with Arabian Space Imaging, a leading provider of aerial survey and geospatial solutions in Saudi Arabia. With their expertise, we conducted drone surveys to capture data from areas that are impossible to reach at ground level—revealing hidden details and relationships between the tombs that are difficult to perceive from below. These high-resolution images will not only enrich our documentation but also provide crucial insights into the tombs’ state of conservation, guiding our future preservation efforts.
Advancing Conservation: Mapei’s Expertise & Sustainable Mortars
This month, our work on mortar testing took center stage through a series of key activities. From in-depth discussions with MAPEI representatives to hands-on testing with locally sourced sand, we made significant progress in refining our conservation techniques. As part of their visit, MAPEI experts provided valuable insights into grouting materials and diagnostic laboratory analysis, helping us develop tailored conservation solutions for Hegra. Their guidance is essential in ensuring our interventions are both effective and sustainable.
At the same time, we focused on mortar formulations using local sand, emphasizing sustainability and compatibility with Hegra’s unique environment. However, before use, the sand undergoes careful processing to remove intrinsic salts that could pose long-term risks. We then sieve it through different mesh sizes to achieve the precise granulometry required for each test batch.
By incorporating local materials and drawing on expert knowledge, we aim to create conservation solutions that are both authentic and environmentally responsible, preserving the integrity of Hegra’s tombs in the most sustainable way possible.
A Fascinating Encounter: Forensic Entomology in Hegra
This month also brought an unexpected but intriguing crossover between archaeology and forensic science. Professor Vanin, a forensic entomologist invited by RCU, gave a fascinating lecture on the use of insects to date human remains. We had the chance to tour Hegra with him, introducing him to some unusual organic degradation patterns we’ve observed on-site. His expertise opened up new perspectives on interpreting biological changes in archaeological contexts.
Art & Music in AlUla: A Sensory Experience
Of course, it hasn’t been all work and no play! In our free time, we’ve been lucky to take part in AlUla’s rich cultural offerings. One of the standout experiences was Tarek Atoui’s exhibition, “Bayt Al Hams (The Whispering House).” This mesmerizing installation explored the role of sound in shaping perception, featuring dynamic acoustic environments and performances. It was a thought-provoking experience that blurred the lines between sound, space, and human interaction.
And the cultural immersion didn’t stop there. Weekends in AlUla offer another unique experience—the Music Hub’s open-air performances, where traditional Arabic musicians fill the air with spontaneous and improvised melodies. The combination of heritage, music, and the magic of the traditional mud-brick house makes these nights truly unforgettable.
With so much happening, from cutting-edge conservation techniques to immersive cultural experiences, this past month has reminded us just how dynamic and multi-faceted our work in AlUla truly is. And as we move forward, we can’t wait to see what new discoveries and experiences the next chapter will bring!
