China Miéville’s fantasy novel Perdido Street Station is mainly set in the fictional city of New Crobuzon. The novel was published in 2000 and is set on the world of Bas-Lag, a setting combining fantasy, industrial imagery, and speculative technology.
New Crobuzon is a vast, polluted city marked by canals, factories, political repression, and inhabitants from several intelligent species. The plot follows scientist Isaac Dan der Grimnebulin, whose attempt to help a winged creature leads to a dangerous outbreak involving predatory slake-moths.
Perdido Street Station is often associated with the New Weird movement, which blends urban fantasy, horror, science fiction, and surreal world-building. New Crobuzon later appears in Miéville’s novels The Scar and Iron Council, though those books focus on different locations and conflicts. Bas-Lag is the wider world, while New Crobuzon is the specific city asked about here.
