The Callanish IV stone circle (Scottish Gaelic: Ceann Hulavig[1]) is one of many megalithic structures around the better-known (and larger) Calanais I on the west coast of the Isle of Lewis, in the Outer Hebrides (Western Isles), Scotland.

The undisturbed deep peat around it gives it the potential for recovery of information regarding contemporary landuse and economy, and possibly other structural evidence.

It is also of national importance as a member of the Callanish group of circles, settings and cairns ('Callanish IV').

Together, this complex is one of the most remarkable Neolithic/Bronze Age site assemblages in N W Europe, and holds great potential for further studies into the date, nature and purpose of megalithic stone circles and settings.
