Compare this picture of the soot-covered entrance to that of the cleaned and restored Street's Law Courts to that of the one taken in Summer 1967. For a few years at least, Street's contemporaries had experienced his bright-stone structure, but within a few years London's heavy pollution darkened the original light colors. What effect do you expect that the polluted surfaces of such Neo-gothic structures had upon the way they were considered in the early years of modernism?
