One of the more obscure consequences of the rise of Hitler and the Nazis in Germany was the arrival in England in 1936 of Gerhard and Maria Bersu. Gerhard Bersu was an experienced German archaeologist who had been forced from office on account of his Jewish background. left; Gerhard Bersu
In 1938 he was invited by the Prehistoric Society to excavate a site at Little Woodbury. The site was one of an increasing collection of ‘cropmark’ sites discovered through aerial photography since the First World War.
Bersu’s excavation of Little Woodbury, and his subsequent report  were a revelation on many levels, and set new standards for excavation, interpretation, and presentation of archaeological sites.
Crucially, he found two circular structures defined by concentric rings of postholes, which he interpreted as round timber buildings. These he reconstructed as having conical roofs and entrance porches. This was not the first timber roundhouse discovered. That credit should probably go to Thomas Wake and his 1936 excavations at Witchy Neuk in Northumberland , but Little Woodbury became the most important for the archaeology of Southern England.
Bersu’s Little Woodbury excavation gave us our first real glimpse of the prehistoric agricultural economy and its built environment, and it established the Iron Age population as competent farmers. This was a long way from primitive people living in pits, as conceived by an earlier generation of archaeologists, but as we will see, still some way from civilisation.
Subsequent excavations would be seen in the light of Bersu's findings, seeking to confirm and expand on these exciting new insights. Understanding a ‘posthole palimpsest’ becomes a lot easier once you know you are looking for circular buildings and four-post granaries. Subsequently, similar structures were found on other sites, with Little Woodbury cited as the parallel to support such identifications. That is not to suggest these things would not have been found elsewhere without the Little Woodbury report, only that its is the beginning of a chain of citations that support such identifications.
