The RSA devised a scheme for commemorating the links between famous people and buildings, by placing plaques on the walls – these continue today as "blue plaques" which have been administered by a range of government bodies. The first of these plaques was, in fact, of red terracotta erected outside a former residence of Lord Byron (since demolished). The Society erected 36 plaques until, in 1901, responsibility for them was transferred to the London County Council (which changed the colour of the plaques to the current blue) and, later, the Greater London Council (the G.L.C.) and, most recently, English Heritage. Similar schemes are now operated in all the constituent countries of the United Kingdom.
