Which London prison is named after a large patch of open land next to it?

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.

In the early 19th century the whole district was open fields, and included several areas of common land. In 1812 an area of 190 acres (77 ha) known as Wormholt Scrubs was leased by the War Office from the Manor of Fulham. This was in order to exercise cavalry horses which until that point had been hacked out in Hyde Park, Belgrave Square and Regent's Park - then known as St. Marylebone's Park. This common land became known as Wormwood Scrubs, 135 acres (55 ha) of which was bought by the War Office in 1878.
