The term rookery was first used in print by the poet George Galloway in 1792 to describe "a cluster of mean tenements densely populated by people of the lowest class".
In 1850, the English novelist Charles Dickens was given a guided tour of several dangerous rookeries by "Inspector Field, the formidable chief detective of Scotland Yard".
[5] A party of six—Dickens, Field, an assistant commissioner, and three lower ranks (probably armed)—made their way into the Rat's Castle, backed by a squad of local police within whistling distance.
Oliver Twist (1838) features the rookery at Jacob's Island:[6] ... crazy wooden galleries common to the backs of half a dozen houses, with holes from which to look upon the slime beneath; windows, broken and patched, with poles thrust out, on which to dry the linen that is never there; rooms so small, so filthy, so confined, that the air would seem to be too tainted even for the dirt and squalor which they shelter; wooden chambers thrusting themselves out above the mud and threatening to fall into it—as some have done; dirt-besmeared walls and decaying foundations, every repulsive lineament of poverty, every loathsome indication of filth, rot, and garbage: all these ornament the banks of Folly Ditch.In Sketches by Boz, Dickens described a rookery:[7] Wretched houses with broken windows patched with rags and paper: every room let out to a different family, and in many instances to two or even three... filth everywhere—a gutter before the houses and a drain behind—clothes drying and slops emptying, from the windows; girls of fourteen or fifteen, with matted hair, walking about barefoot, and in white great-coats, almost their only covering; boys of all ages, in coats of all sizes and no coats at all; men and women, in every variety of scanty and dirty apparel, lounging, scolding, drinking, smoking, squabbling, fighting, and swearing.In The Rookeries of London (1850)[citation needed] Thomas Beames also described one: The Rookery... was like an honeycomb, perforated by a number of courts and blind alleys, cul de sac, without any outlet other than the entrance.
Here were the lowest lodging houses in London, inhabited by the various classes of thieves common to large cities… were banded together… Because all are taken in who can pay their footing, the thief and the prostitute are harboured among those whose only crime is poverty, and there is thus always a comparatively secure retreat for him who has outraged his country's laws.
Sums here are paid, a tithe of which, if well laid out, would provide at once a decent and an ample lodging for the deserving poor; and that surplus, which might add to the comfort and better the condition of the industrious, finds its way into the pocket of the middleman....Kellow Chesney gives a whole chapter to the rookeries of London.
