Landforms are past (or present) interpretations within a landscape which enable the land to represent meanings found within astronomical time or ideas about the ordering within any centre and its environs. There is evidence for the widespread use of landforms in prehistoric and ancient cultures.

The megalithic was the most visible of several phases of building types, only recently identified as the actual built heritage of the British "neolithic" period; that is, between the widespread building of long and round barrows and the last stone circles in Britain. Avebury and Stonehenge were just starting to be built as stone circles towards the end of the main Cursus-building period, dated as between 3600 and 2800 BC.
