Excavations were undertaken in 1937 by R. G. Collingwood and continued in 1939 by Gerhard Bersu. The excavations showed that the ditch had been cleared out and reshaped and the entrance through it made narrower in modern times. Collingwood claimed to have identified a number of structures, represented by postholes, and identified a "cremation trench" near the centre of the site. Bersu, however, contradicted most of Collingwood's findings, arguing that the posthole features were not of archaeological significance, and he found no evidence of cremation burning, although he accepted that there might be a disturbed grave. However Grace Simpson (1998), the daughter of the excavator F.G. Simpson, and Stephen Leach (2019) have queried Bersu’s work and largely rehabilitated Collingwood as an excavator.
