The County Hall, the home of London government from 1922 to 1986. LCC 1889-1965. GLC 1965-1986

Faced with the imminent abolition of the Greater London Council on 31st March 1986, a number of councillors decided that a blue plaque at the GLC's headquarters, the vast County Hall building on the southern embankment of the thames, would be a appropriate record to that which was being lost. Angry with the manner of the authority's abolition, the principal aim was to leave a permanent record that could not easily be obliterated by the successor authority. The standard roundel design was modified to incorporate a distinctive border of laurel leaves, with the arms of the GLC and its predecessor the London County Council placed top and bottom. A second plaque at the site, conceived once preparations for the County Hall plaque were under way, commemorates the Inner London Education Authority. Both plaques were unveiled on the last working day of the GLC, 27th March 1986, by the council's leader Ken Livingstone.
