 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 Coldrum Stones alongside the other Medway Megaliths . In 1926 , the Coldrum Stones were given to The National Trust , who dedicated it as a memorial to the <unk> historian Benjamin Harrison . A plaque was erected to mark this , which erroneously termed the monument a stone circle ; in 1953 , the archaeologist Leslie <unk> expressed the view that " it is hoped that this error may be rectified in the near future " . Still owned by the Trust , the site is open to visitors all year round , free of charge . On their website , the Trust advises visitors to look for " stunning views from the top of the barrow " . John H. Evans characterised the site as " the most impressive " of the Medway Megaliths , while <unk> described it as " the finest and most complete " of the group .
