castlerigg stone circle. keswick. the mountains and fells that surround the circle on all sides create a natural amphitheatre. its location on a plateau of castlerigg fell is so positioned to be locked into these features. it has been demonstrated that certain stones align with the rising and setting of the sun and the moon as they appear and disappear behind the mountain fells and thereby mark the celestial calendar; the solstices and equinoxes and the lunar movements. the rectilinear feature at the western side of the circle has clough head as its backdrop with great mell fell and penwith to its north and the dodds and high rigg to its south. the large stone set perpendicularly towards the centre of the circle aligning with a smaller stone on the opposite side and the midwinter setting of the sun. #astronomy #ancientastronomy #ancientwisdom #ancientmathematics #prehistory #neolithic #stonecircle #stonecircles #cumbria #castleriggstonecircle #castlerigg #cumbrianfells #cloughhead #penwith #greatmellfell #midwintersolstice #midwinter #midwintersun
