Hanwell Park was a farming estate in the London Borough of Ealing west London. The estate was finally broken up by 1886 after Sir Montagu Sharpe had sold the holding he had inherited. Brent Valley golf club was formed from the estate of The Grove - a landed estate of 29 acres formed on the breakup of the much larger Hanwell Park estate in 1837 and enfranchised in 1860. Nearby is Cuckoo Hill, the site of a battle between Romano-British and Saxons in the sixth century known as Blood(y) Croft and this bloodshed is a suggested origin of the name Hanwell; haenwael being a slaughter on high ground.
