A little-used name for the area surrounding the western half of Old Street. After its marshes were drained in the sixteenth century, a hospital was built for plague victims, which stood until 1736. From medieval times until the slum clearance programme of the 1870s its position on the edge of the City made St Luke’s a haven for all kinds of prohibited activities, from astrology and wizardry to bear-baiting and prostitution. Thieves and pickpockets could make regular forays into the City and then lose any pursuer in the maze of courts and alleyways around Whitecross Street, which nowadays has a more respectable weekday market.

The reputation of St Luke’s as a ‘rookery’ – a zone of criminality – reached a peak in the first half of the nineteenth century. ‘Flash houses’ – drinking dens and lodging houses where criminal plans were laid and stolen goods fenced – were more numerous here than anywhere else in London. By 1900 southern St Luke’s had become a district of workshops and warehouses, with new tenement blocks providing homes for law-abiding citizens. However, many of the worst elements simply decamped to the other side of Old Street and this part remained disreputable until the 1930s. St Luke’s primary school was founded in 1698. It is justifiably popular and oversubscribed.
