My favorite claim is about the #HundredHorseChestnut — a #SweetChestnut #Castanea_sativa and not a Horsechestnut! — with a purported trunk circumference of 190’ / 57.9 m and presumed diameter of ~60’ / 18.3 m, by far the largest of ANY #BigTree ! Sadly, it seems quite unlikely this #Tree — which is still around! — ever had a single trunk that was actually such a size.
