        Drawn by  en:User:Adamsan from sources:
        
         - Cleal, Walker, & Montague, Stonehenge in its Landscape (London, English Heritage 1995)
 
         - Pitts, M, Hengeworld (London, Arrow 2001)
 
        
        Key to plan:
        
         - 1 = The Altar Stone, a six ton monolith of green  micaceous sandstone from Wales
 
         - 2 =  barrow without a burial
 
         - 3 = "barrows" (without burials)
 
         - 4 = the fallen Slaughter Stone, 4.9 metres long
 
         - 5 = the Heel Stone
 
         - 6 = two of originally four Station Stones
 
         - 7 = ditch
 
         - 8 = inner bank
 
         - 9 = outer bank
 
         - 10 = The Avenue, a parallel pair of ditches and banks leading 3 km to the River Avon
 
         - 11 = ring of 30 pits called the Y Holes
 
         - 12 = ring of 29 pits called the Z Holes
 
         - 13 = circle of 56 pits, known as the Aubrey holes
 
         - 14 = smaller southern entrance
 
        
        The site as of AD 2004. The plan omits the trilithon lintels for clarity. Holes that no longer, or never, contained stones are shown as open circles and stones visible today are shown coloured, grey for  sarsen and blue for the imported stone, mainly  bluestone.
