Old Nichol

The Old Nichol, also known as the Nichol or the Old Nichol Street Rookery, was an area of housing in the East End of London, between High Street, Shoreditch, and Hackney Road in the north, and Spitalfields in the south. The main streets within the Old Nichol were Boundary Street, Old Nichol Street, Half Nichol Street, The Mount and Church Street.] The slum was located in the western boundary of Bethnal Green, with six of its streets across Boundary Street located in Shoreditch. The Old Nichol was home to 5,719 people, living in a dense network of about 30 streets and courts. The late 18th-century houses included workshops and stables.

In Victorian Britain of the 1880s, the Old Nichol was London’s most notorious slum.[3] The “evil” reputation of the Old Nichol owed much to Arthur Morrison’s fictionalised account of it in A Child of the Jago (1896), and to sensational articles by Rev. Osborne Jay of Holy Trinity Church, known as Father Jay, on whom Morrison relied for information
