New Southgate is a residential suburb straddling three Outer London Boroughs: a small part of the east of Barnet, a south-west corner of Enfield and in loosest definitions, based on nearest railway stations, a small northern corner of Haringey in North London, England where estates merge into Bounds Green.
Its first church, founded in 1873, was among organisations opting for the newer name, New Southgate, rather than the older hamlet name Colney Hatch which from 1851 became more use-specific. The gradual demise of the former place name use is shown by New Southgate railway station, renamed five times. Changes in this terminology reflect social stigma to a large residential institution, in this case the Colney Hatch Lunatic Asylum, built in 1851, which co-provided for Middlesex and as such continued to serve much of London after London County Council was founded in 1889. The later mental health hospital closed in 1993 and has been redeveloped into two housing estates, Princess Park Manor and Friern Village in New Southgate.
