Lightning strikes gunpowder factory in Luxembourg, killing hundreds

On this day in 1807, lightning hits a gunpowder factory in the small European country of Luxembourg, killing more than 300 people. Lightning kills approximately 73 people every year in the United States alone, but victims are almost always killed one at a time. The Luxembourg disaster may have been the most deadly lightning strike in history.

The earth experiences 8 to 9 million lightning strikes every single day. In a typical year, the United States will see about 70,000 thunderstorms somewhere in its territory. This produces approximately 20 million lightning strikes annually. A bolt of lightning can reach 50,000 degrees Fahrenheit in instant heat. There are 100 million volts in an average lightning bolt, which can be as much as five miles long.

In 1807, Luxembourg was occupied by Napoleon’s army. The French dictator used the country to stockpile weapons and ammunition. Many underground bunkers were built for this purpose. In the southern Luxembourg city of Kirchberg, a fortress built in 1732 was used as an armory.

When lightning struck the fortress on June 26, the ammunition housed within ignited on contact, causing a massive explosion. Two entire blocks were completely razed by the blast, which caused several other fires to rage nearby. The London Times later reported, "This city has been plunged into the greatest consternation and distress."
