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.
