 They can be divided into two separate clusters : one to the west of the River Medway and the other on Blue Bell Hill to the east , with the distance between the two clusters measuring at between 8 and 10 km . The western group includes Coldrum Long Barrow , Addington Long Barrow , and the Chestnuts Long Barrow . The eastern group consists of Kit 's Coty House , Little Kit 's Coty House , the Coffin Stone , and several other stones which might have once been parts of chambered tombs . It is not known if they were all built at the same time , or whether they were constructed in succession , while similarly it is not known if they each served the same function or whether there was a hierarchy in their usage .
