The Great Sacred Monuments of Stenness

There were at least three wells of notes in the Stenness region. The sacred well stood in a marshy field with many springs below a farm (HY33721048 ?). This describes a different location from that ascribed to Bigswell which is on a slope across from the modern farm (Upper Bigswell). Both these are well SSE of Maes Howe however. But at the lochshore below the Ring of Brodgar is/was placed the “fairy well” (HY29541300).
