The district was created by the Metropolis Management Act 1855, and comprised the civil parish of St Giles in the Fields and St George Bloomsbury, Middlesex: the two parishes had been combined for civil purposes in 1774. The district was abolished in 1900 and its former area became part of the Metropolitan Borough of Holborn. The civil parish was abolished in 1930. It is now part of the London Borough of Camden.
