About Balmerlawn
Balmerlawn
Human settlement in England

Balmer Lawn is the name of a large New Forest Lawn located in an amphitheatre of woodland in the New Forest National Park in Hampshire, England. It is just north of the village of Brockenhurst. The lawn comprises about 500 acre of open low land grazing frequented by Forest stock. The name of the area comes from a distortion of the historical name Palmers Water - reference “Comyn’s New Forest” of 1817. Palmers Water was in fact a small settlement which has long since disappeared but was located to east of the ford on the Brockenhurst to Beaulieu road. The water being the Lymington River which separates Brockenhurst and the small settlement of Balmerlawn on the south side of the grazing lawn. The lawn of course remained and over time Palmers became Balmer, perhaps aided by the local dialect.
