What is "pitshanger"

Pitshanger (sometimes referred to as Pitshanger Village) is a small but busy local suburb, centred on the shops in Pitshanger Lane, located about 1 mile north of Ealing Broadway in west London. First mentioned in 1493, possibly meaning an area of sloped woodland frequented by birds. It contains numerous small shops, several cafes, two pubs, two churches, a school, and a park (Pitshanger Park), and is often taken to also include parts of the nearby Brentham Garden Suburb. It is served by buses E2 and E9 and night bus N7.
