Harefield already had a priest when the Domesday survey was made in 1086, which is why the Ancient Yew Group takes it that there was a church at Harefield back then. The yew in St Mary's churchyard is the one tree here the group counts as ancient. Its size is harder to pin down. The group's earlier record put it in the class of yews more than seven metres round. Its 2022 list for the Diocese of London puts it at five to seven metres instead. Under the group's own rule of thumb, a yew that size is likely more than 500 years old. Nobody has published a measured girth, so the band is wide and the age is an estimate from size, not a count of rings. No legend comes attached to it in anything we have read. What it has is a churchyard south of the village with a church presumed there since Domesday, and by the best reckoning available more than five centuries of growth. The most recent dated photographs we have found are from January 2014. If you visit, tell us how it is doing, and if you have a tape, tell us what it measures. The churchyard is free and open to the public.
