it devised a scheme for remembering the links between famous people and buildings by placing plaques on the walls — these continue today as "blue plaques" which are administered by a range of government bodies. the first of these plaques was, in fact, of red terracotta placed on the outside of a former home 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 and most recently english heritage. similar schemes are now operated in all the constituent countries of the united kingdom.
