Leskernick North Circle was added to the Historic England List (go to Links) on 16/10/19.
'The stone circle comprises a recumbent stone (4m long) a little north of the circle’s centre with 25 stones in an almost-perfect circle approximately 23m in diameter.'
The above quote is an extract from Historic England's summary of Leskernick North Circle. A more detailed account is contained therein.
According to Historic England turf was cleared round the stones in 2018 so the circle will perhaps look more complete now.
Clearing both North and South Circles and the stone row. Clearance to be interpreted as stated here..
"the aim of the clearance would be to bring the hidden parts of the circles and stone row ‘back to life’ by sympathetically removing the vegetation and turf ‘carpet’ off the stones without damage taking place and without any soil being removed below the exposed top surfaces"
