Flinders Petrie in 1878, and the first photograph of the site was published in 1893. In 1910, F.J. Bennett undertook an excavation at the site, revealing the bones of 22 individuals, of both sexes and various ages, along with a pot sherd and a flint saw, which had been buried in the north-western part of the monument. Further bones were excavated in a 1922 excavation by E.W. Filkins, but these were largely lost during the Second World War. In 1926, the monument was given to The National Trust who dedicated it as a memorial to the local historian Benjamin Harrison. In 1946, the folklorist John H. Evans noted that locally, the Coldrum Long Barrows had come to be associated with the folkloric trope of the countless stones. The site is open free of charge to the public throughout the year, and can be accessed by foot along Coldrum Lane. Addington Long Barrow Addington long barrow is situated about 250 metres north of the parish church in Addington, and can be accessed via one of two small roads that branch off from the A2. A peristalith, the monument is approximately 60 metres in length, although its width tapers, from 14 metres at the east to 11 metres at the west. The stone chamber was apparently on the eastern end, although has now collapsed. The monument is now bisected by a road running through the middle of it. The mound of the barrow is currently one metre high, although would initially have been much higher, having succumbed to millennia of weathering. The first published record that commented on the existence of stones at the site was in 1719, although they would only be described as the relics of a prehistoric survival in print in 1779, when it was erroneously described as a stone circle and compared to Stonehenge. When the road was widened and deepened in 1827, two of the stones from the revetment curb were removed and deposited in the corner of the wood to the south of the barrow. The site was excavated circa 1845 by a local vicar, the Reverend Lambert Larking, who allegedly found some evidence of ceramics; it has also been asserted, although not proven, that he discovered human bones at the site. When Thomas Wright explored it c.1850, he was aided by a local man who enthusiastically believed that a crock of gold would be buried
