monument, taken by George Clinch, appeared in a 1908 volume of the Victoria County History series. In his 1924 publication dealing with Kent, the archaeologist O. G. S. Crawford, then working as the archaeological officer for the Ordnance Survey, listed the Addington Long Barrow alongside the other Medway Megaliths. Ronald Jessup included the Addington site in his 1970 book, South East England, there describing it as "mostly overgrown". In 1981, members of the Kent Archaeological Rescue Unit conducted a measured survey of the monument. In 2005, Ashbee noted that he had found evidence of recent metal detectoring activity at the site. In May 2007, the archaeologist Brian Philp was conducting his regular inspection of the monument when the current landowner pointed out to him an area where the road was subsiding. Philp alerted Kent County Council, who arranged for contractors to investigate the reason for the subsidence, which proved to be decades of rabbit burrowing beneath the tarmac. Archaeologists from Kent Archaeological Unit visited the site during the work, discovering a buried sarsen. Comparison with older records revealed that this stone had once been upright but had been buried where it stood in the 19th century by workmen who were replacing the trackway with a paved road.
