In Arthur Lunn’s interesting little book on Sarsens in Hampshire, specifically around Cove, Farnborough, he makes an interesting statement about a ley line running through Tower Hill, Cove (the book is about the existence of a stone circle on Tower Hill now, unfortunately long gone) The line runs from Hornley Common barrow (just behind Blackdown Lodge on an army barracks and sadly inaccessible) through a recumbant sarsen stone on West Heath (of which I have been unable to find – I wonder if it’s been swallowed by the motorway) past Tower Hill and on to Albert Road barrow. The line is very close to mid-summer sunrise and mid-winter sunset.
The barrow is in someone’s garden now, but still nicely visible from the road.
