The stainless steel box-shaped structure was designed by modern movement architect Rodney Gordon in 1959 and built in 1961, on the centre of what was the northern roundabout of the Elephant and Castle gyratory system. It commemorates Michael Faraday's importance as a scientist and was placed at Elephant and Castle because Faraday's birthplace is nearby in Newington Butts.The interior of the construction contains a London Underground electrical substation for the Northern line and Bakerloo line (somewhat appropriate for a memorial to one of the great pioneers of electricity). Rodney Gordon originally designed the box clad in glass, intending the workings of the transformer to be seen. The possibility of vandalism prevented this, so the design was changed to a metal casing.
