Carlton Hill is an inner-city area of Brighton, part of the English city and seaside resort of Brighton and Hove. First developed in the early and mid-19th century on steeply sloping farmland east of central Brighton, it grew rapidly as the town became a fashionable, high-class destination. Carlton Hill's population was always poor, though, and by the early 20th century the area was Brighton's worst slum: overcrowding, crime and disease were rife. Extensive slum clearance in the mid-20th century introduced high-density tower blocks, but some old buildings remain: in 2008, Brighton and Hove City Council designated part of Carlton Hill as the city's 34th conservation area.
