This site was discovered in 1979 during one of the rare and brief initial flights inspired by the works of Roger Agache. The flights became more frequent and thousands of photographs were taken all over the Champagne-Ardennes region. The whole of the site at Acy-Romance was gradually revealed year by year. Following the photographs of "Le Terrage", came the circular Bronze Age enclosures at La Croizette, then the large rectangular enclosure of the necropolis from the late Gallic period at the same location, the enclosures at "La Noue Mauroy" and a few years later the ones at "La Noue de Barue" and "La Prêle". The settlement at "La Warde" has never been seen properly as a whole and "Les Carrières" revealed new structures in 2011 in the small section not yet excavated. 2009 was a spectacular year, with the appearance of new marks in a wheat field at "La Noue Mauroy", a sector surveyed from the air dozens of times every year and in every season. These marks were found to correspond to grain stores from the settlement in the 5th century BC whose necropolis had been discovered from the air a few years earlier a few hundred metres to the west.
The aeroplane has made a substantial contribution to the history of the research and excavation of the site at Acy-Romance.
