Satellite imagery and field surveys reveal a network of Garamantian settlements in the Libyan desert
Libya – A report in India’s English-language newspaper The Times of India reviewed how satellite imagery and field surveys have uncovered more than 100 archaeological sites of the Garamantian civilisation in Fezzan, including farms, villages, fortified towns and castles, most dating to between the first and fifth centuries AD.
Research in old photographs and space data
The report, which Al-Marsad followed and translated, said a University of Leicester team led by scholar David Mattingly spent years analysing high-quality space data for Fezzan — some originally gathered to assess the oil sector — alongside aerial photographs from the 1950s and 1960s.
In early 2011 the team gained a limited chance to check on the ground the faint geometric shapes seen in the desert images, finding them to be remains of farms, fortified towns and walled villages. Unlike nearby Germa, the Garamantian capital, which has seen partial excavation, these sites had not previously been surveyed or documented systematically, the report said.
A different view of a desert civilisation
Outside observers long treated south-western Libya’s desert as a barren, hostile setting that offered archaeologists little beyond scattered Roman references to rebellious desert tribes, the report said, blaming limited access for international researchers and insufficient priority for pre-Islamic history.
Uncovering what had remained hidden for about two millennia required combining satellite techniques with scarce fieldwork opportunities. Outsiders had known the Garamantes, indigenous people of the desert, mainly from Roman and Greek texts the report called hostile and distorting. Against portrayals of them as rebellious nomads on imperial fringes, the evidence showed mud-brick complexes resembling castles, walls still standing up to four metres high, cairn tombs, wells, and traces of farming systems and irrigation networks that supported oasis agriculture in an area that now receives little rain.
An organised state, trade and irrigation
The study, known as the Trans-Sahara Project, received an advanced grant from the European Research Council, which described the findings as among the most important archaeological discoveries from remote sensing in North Africa, the report said. The Garamantes were close neighbours of the Roman Empire, and the results depict an organised state with towns, a written language and techniques for farming in a harsh environment — not merely a polity absent from Roman awareness. That state helped open trade routes across the Sahara, linking the Mediterranean world with regions further south.
Field verification and the find’s significance
Aerial images alone were not enough to date the structures; Garamantian pottery samples collected during the early 2011 survey supported the proposed chronology before researchers had to leave Libya amid the unrest that led to the overthrow of the late Colonel Muammar Gaddafi. Later improvements in political stability allowed further surveys that confirmed the remains belonged to the pre-Islamic period and showed a notable level of preservation, the report said.
The scale of settlements around Germa shifted the picture from a single important city to an integrated network of linked communities. The European Commission’s research information service later presented the findings more widely, highlighting their impact on views of early African state formation. For Libyan heritage bodies, the report argued, the discovery goes beyond archaeology: it presents important towns that arose locally rather than through outside powers such as the Greeks or Romans, and rebuilds the picture of a full civilisation by reading satellite data.
