It was a day of death and destruction the scale of which has seldom been witnessed in Edinburgh - and the yet the terrifying incident is now largely forgotten.
At around 12.30pm on Tuesday July 16, 1901, an ear-splitting explosion broke out at the Tod Brothers flour mill in Baker's Place, Stockbridge, leaving a trail of devastation in its wake and claiming the lives of six people.
The tremendous blast came from behind the offices of the busy mill, which employed around 35 people, where workers had been engaged in the removal of an old gas engine that was to be replaced by a new electric system.
