Later in the Neolithic, burial practices tended to place greater emphasis on the individual, suggesting a growing social hierarchy and a move away from collective burial.[26] One of the last chambered tombs erected was Bryn Celli Ddu in Anglesey, Wales, built long after people stopped building them across most of Western Europe. The conscious anachronism of the monument led excavators to suggest that its construction was part of a deliberate attempt by people to restore older religious practices that were extinct elsewhere.[27]
