One of London's lesser-known heritage monuments is this reminder of the London Soap and Cosmetic Company at Clarence and South streets. The factory, here from 1875 to 1984, burned in April 1985, at which time it was the oldest surviving soap factory in Canada. These machines were taken from the ruins and made into a monument by the Ontario Society for Industrial Archaeology. Pretty cool, eh? It's tributes like these that add interest and entertainment value to our streets, especially when people come across them unexpectedly.
