City of London School for Girls

City of London School for Girls, or CLSG for short, is an independent[?] girls' school located in the Barbican[?] complex in the City of London in London, United Kingdom. It is the sister school of the City of London School[?], an independent boys' school somewhat nearer the river Thames. Intake is from age 7 to 18, though many of its pupils enter at 11, and similarly join other independent schools for the sixth form (17-18).
