How virtual reality is opening up some of the world’s most inaccessible archaeological sites
Brendan Cassidy, University of Central Lancashire and David Robinson, University of Central Lancashire
We often associate virtual reality (VR) with thrilling experiences we may never be able to have in real life – such as flying a jet fighter, exploring the oceans or going on a spacewalk. But researchers are also starting to use this technology to study and open up access to archaeological sites that are difficult to get to.
An archaeological site can be inaccessible for a range of reasons. It might be in a remote location or on private property, the archaeological remains may be fragile, or it might just be difficult or dangerous to get there.
Just over an hour’s drive north from Los Angeles is the Wind Wolves Preserve. At nearly 100,000 acres, the preserve protects a wide range of endangered and threatened species in the heart of the most populous state in the US.
It also hosts two remote archaeological sites situated in the San Emigdio Hills. Pleito, one of the most elaborately painted rock-art sites in the world, and Cache Cave, with one of the most significant in-situ collections of perishable objects, including baskets, ever discovered in the American West. The oldest of the rock paintings and baskets appear to be over 2,000-years-old. However, exploring it is problematic. The paintings at Pleito, found on exfoliating sandstone, are extremely fragile. Meanwhile, the Cache Cave is a complex, narrow cave system.
Yet these sites are of great cultural importance to local Native Americans, especially the Tejon Indian Tribe. The hands of some of their ancestors painted the rock art, while other highly skilled basket makers worked for hours on making some of the world’s finest basketry. Until recently, the majority of the Tejon tribes people were unable to visit the Pleito cave site due to its inaccessibility and fragility.
Now our team of researchers from the University of Central Lancashire in the UK has created a VR model of the sites. We did this by taking images with a digital camera and performing laser scanning of the site. Using “reality capture” techniques like photogrammetry – which helps make measurements from photographs – we could then develop a VR prototype.
We tested the prototype at the offices of the Wind Wolves Preserve and the Tejon tribe, respectively, in the summer of 2017. The response was profound, with younger tribal members responding particularly well in an environment similar to “gaming”. Equally, the simulation proved effective for use by the elder members of the tribe, some of whom have mobility issues visiting the preserve and its rugged terrain.
We also tested the software at the actual site of Pleito with the Tejon Indians. Two tribal members who could not make the climb to the cave instead used the VR headset on flat ground nearby. This allowed them to experience the environment and to “be” in the landscape while still exploring the paintings. This, as far as we are aware, was the first time Native Americans have used VR in the field to reconnect with their own past.
The research provides an innovative platform for tribal members to engage with sites and practices no longer in living memory as a form of cultural restoration. Importantly, it also provides an effective way to engage young tribal members within ancestral spaces and practices.
As well as opening access to remote archaeological sites, we are now able to construct what we term an “enhanced reality” experience. Cutting edge archaeological image processing techniques such as DStretch and Reflective Transformation Imaging can be used to overlay digitally enhanced textures directly over the cave geometry. This allows people to view details of the site that are difficult to see with the naked eye.
For example, research investigating pigment recipes used within the different layers of painting on the site helped us to display the separation of the layers on the cave. It also enabled us to show the site as it would have looked through different points in time.
This really shows how VR simulations of archaeological sites can offer unique ways to experience, engage and explore scientific data.
As a visualisation tool, new opportunities are now arising to use immersive technologies like VR to conduct research. Innovative work at the Allosphere – a facility at the University of California, Santa Barbara, which helps make visual representations of data – has enabled researchers to analyse multiple data sets in ways not previously possible.
In our work in California, we are investigating how to use VR to help field research by using immersive reconstructions of previous season’s excavations to aid in new ones as we dig deeper within the cave deposits. That way, we can actually see previous layers that we have removed and better contextualise the new layers we are exposing.
The technology can also be of great use in teaching. We are sharing the models of the Californian sites with our archaeology and anthropology students, offering unique and novel opportunity to explore the rock art, handle and inspect the baskets and even use native technologies such as the bow and arrow.
VR technologies are starting to open up remote access to other sites around the world too. From the British Museums documentation of African rock art sites to the Scan Pyramids Project opening access to the iconic monuments of Giza, to an immersive interaction with Nikola Tesla and his laboratory, the application of immersive technologies are proliferating across the globe.
The most creative of these projects include scientific information to make them more than simple replications – enhanced learning environments where scientific knowledge can inform the public about the past. Excitingly, this offers entirely new ways to learn from old sites, without damaging them.

Old sites, new visions: art and archaeology collide in Cyprus
Craig Barker, University of Sydney and Diana Wood Conroy, University of Wollongong
Over the past two decades Australian archaeologists have been slowly uncovering the World Heritage-listed ancient theatre site at Paphos in Cyprus. The Hellenistic-Roman period theatre was used for performance for over six centuries from around 300 BC to the late fourth century AD. There is also considerable evidence of activity on the site after the theatre was destroyed, particularly during the Crusader era.
The excavation of the site, and of the architectural remains in particular, is contributing significantly to our understanding of the role of theatre in the ancient eastern Mediterranean and the development of theatre architecture to reflect contemporary performance trends in the ancient world.
When we return to the site this month we will take archaeologists, surveyors, architects, specialist researchers of ancient materials, students and volunteers. We will also take contemporary artists.
As incongruous as this relationship sounds, the project is part of a wider momentum in contemporary Australian art that lauds working across disciplines. And the link between antiquity and today allows for fascinating insights to the benefit of both.
At the birth of archaeology as a discipline in the 19th century, it was a common practice to take artists on expeditions. Illustrations of exotic sites and impressive archaeological finds filled journals in Europe and the United States, such as the Illustrated London News. These reports allowed an eagerly awaiting audience to participate in the rediscovery. The rediscovery of ancient artist traditions had a profound effect on art movements of the 18th and 19th century too, from Neoclassicism to French Realism.
By the 20th century, however, archaeology as a discipline had become very focused on objective observation and detailed evidence-based analysis. Archaeological illustration became a form of technical drawing or scientific illustration, and the archaeological photograph developed clear standards for accurate recording. Any creative and emotive response to the past was pushed aside.
Recently, however, there has been something of a renewal of this relationship between the scientist and the artist. Mark Dion in 1999 used archaeological finds from London as the basis of his work Tate Thames Dig, arranging found objects in a cabinet for display.
In Australia, Ursula K. Frederick, who has a background in archaeology, explores the aesthetics of car cultures in Australia, Japan and the US. Izabela Pluta’s photographs explore ruin and place.
The responses of artists working in Paphos are often compelling, enabling ways of thinking that archaeologists had not previously considered. Media artist Brogan Bunt, for example, speaks of the irony of ephemeral digital platforms that cause what was new technology in 2006 to be unusable by 2017. For him, the ancient theatre site has maintained its identity for millennia, while digital virtual heritage is far more fragile than the places it sets out to document and preserve.
The following are works from the exhibition Travellers from Australia to be held in Paphos as part of the Pafos2017 European Capital of Culture festival.
“My photographs combine visual exploration of actual sites and objects with original research into the quantum leap made by digital photography.” – Bob Miller
“I perceive the photography of sites as a memory aid, as a historical resource, as well as a reflective form of art.” – Rowan Conroy
“By mixing artistic and archaeological images we get a new grammar of looking.” – Derek Kreckler
“My research proposes a relationship between material landscapes and the immaterial and invisible spiritual, psychological and intellectual landscapes created through the artist’s gaze.” – Lawrence Wallen
“In my work I approach memories somewhat like an analyst, but perhaps more like a reflective archaeologist.” – Jacky Redgate
“Animation is for me, the physical, material perception of time.” – Hannah Gee
“The artistic motif crosses between eras, travelling back and forth in a temporal instability.” – Angela Brennan
“Drawing is a tool of thought allowing a larger framework for other meanings to emerge.” – Diana Wood Conroy
“My casting and patination process makes a connection to the narratives of archaeology.” – Penny Harris
“Digital ephemerality draws into curious relation with the loss and disappearance affecting the ancient world.” – Brogan Bunt
The Paphos Theatre Archaeological Project conducts its excavations and research under the auspices of the Department of Antiquities of Cyprus.

ANZAC: First Landings at Gallipoli – Turkey
Around the world today, Australians and New Zealanders will be remembering the fallen, on what is now known to us as ANZAC Day. ANZAC Day is remembered annually on the anniversary of the first major military action fought by the Australian and New Zealand Army Corps during World War I. On this day in 1915, ANZAC troops landed on the beach of what is now Anzac Cove. Gallipoli was evacuated in December 1915. The campaign was a disaster, but a legend was born out of it, that of ANZAC.

ANZAC Day was officially held for the first time in 1916 with a number of ceremonies and services held in Australia, New Zealand, England and Egypt. It was not until 1927 however, that Australians held their first uniform remembrance day and it became more established after that.
From the Second World War, ANZAC Day took on a broader significance, as a day to remember the men and women who made the ultimate sacrifice for their country in both Australia and New Zealand.
