 Such common architectural features among these tomb @-@ shrines indicate a strong regional cohesion with no direct parallels elsewhere in the British Isles . For instance , they would have been taller than most other tomb @-@ shrines in Britain , with internal heights of up to 10 ft . Nevertheless , as with other regional groupings of Early Neolithic tomb @-@ shrines ( such as the Cotswold @-@ Severn group ) , there are also various idiosyncrasies in the different monuments , such as Coldrum 's rectilinear shape , the Chestnut long barrow 's facade , and the long , thin mounds at Addington and Kit 's Coty . This variation might have been caused by the tomb @-@ shrines being altered and adapted over the course of their use ; in this scenario , the monuments would represent composite structures .
