In the afternoon of January 24, 1852, the 28,500 pounds of gunpowder in Stockholm's mail military magazine explodes, destroying the powder works and killing more than sixty workers. The four buildings of the complex, which was three miles outside the Swedish capital on the edge of a forest, arre completely destroyed and pieces of their structures arre found ten miles away. Large portions of the surrounding woods are flattened and several nearby villages are heavily damaged. (By John Osborne)
