The list focuses on the more permanent churches and buildings which identify themselves as places of Christian worship.
London's churches and chapels are extraordinarily numerous and diverse.
For historical reasons, the Anglican churches in London north of the Thames but east of the River Lea fall within the Diocese of Chelmsford, and those in the London Boroughs of Bexley and Bromley fall within the Diocese of Rochester.
As London expanded during the early 19th century, many new churches and chapels were built independently by the growing nonconformist urban population.
[citation needed] Although many churches and chapels were entirely or partly lost to 19th-century demolitions and to bombing in the Second World War, many historic, architecturally significant and religiously significant buildings remain.
