Wormwood Scrubs, known locally as The Scrubs (or simply Scrubs), is an open space located in the north-eastern corner of the London Borough of Hammersmith and Fulham in west London. It is the largest open space in the Borough, at 80 ha (200 acres), and one of the largest areas of common in London. The eastern part, known as Little Wormwood Scrubs, is cut off by Scrubs Lane and the West London Line railway. It has been an open public space since the Wormwood Scrubs Act of 1879.
