On the afternoon of February 15 1894, a French anarchist named Martial Bourdin was killed on the slope beneath the Royal Observatory in Greenwich Park when the bomb he was carrying detonated accidentally. His intentions have always been unclear, but at the time it was generally assumed that his aim was to blow up the scientific institution, site of the Prime Meridian, in the name of revolutionary anarchism.
