The Avenue formalises the earlier north-eastern entrance into Stonehenge.
Outside the ditch, the Heel Stone stands near the middle of the Avenue, just before it enters Stonehenge. When
viewed from the centre of the stone circle, it shows the direction of the midsummer sunrise. Excavations in 1979
suggest that the Heel Stone may have been one of a pair.
Immediately within the bank, the entrance was marked by three standing stones, one of which remains lying on the
ground (now known as the Slaughter Stone).
