The Landscape Around Unstan

When Unstan was first built the sea-level was about a meter lower than today so that the tomb sat further from the shore and the Loch of Stenness would have been fresh water.  Shallow reed beds may have lined the shore, which would have been rocky.  The great stone circles of the Ring of Brodgar and the Stones of Stenness would have been visible across the loch, together with the buildings at the Ness of Brodgar.  Small stands of woodland still existed across the landscape of Orkney at the time, separated by cleared fields and small farm steadings.
