Historians have already established the fact that the circle of stones is aligned with the midsummer sunrise. However, it was Tim Daw claimed that the tallest one is lined up with the midwinter sun.
Mr Daw said: "The largest stone at Stonehenge is not where it 'should' be, it is twisted.
"This stone, Stone 56, is the tallest one at the end of the inner horseshoe of sarsen stones.
"Because it was put back to the vertical in 1901 it has been assumed that the twist is the result of the modern excavators botching the job.
"My research shows that not only was the standing stone out of symmetry with the central solstice alignment originally, but that its now fallen partner had also been, and so were surrounding stones, including the Altar Stone."
It was previously thought that the stone were put back at the wrong angle when it was re-erected in 1901.
"The stones point to the midwinter solstice sunrise and midsummer sunset," he said.
"This alignment had been missed by previous investigators... as they used an idealised plan rather than an actual plan for their calculations."
"This isn't some nebulous sighting line on a distant star; this is 100 tonnes of stone deliberately pointing to the major event at the other end of the day the rest of the monument celebrates.
"One stone out of line might be a coincidence but that it is five of the major stones, at least, shows it was a designed feature.
"It shows what can be discovered by simple observation even in such a well-researched site as Stonehenge."
