Dublin Gunpowder Disaster

The Dublin Gunpowder Disaster was a devastating explosion that took place on the quays of Dublin on March 11, 1597. The explosion demolished as many as forty houses, and left dozens of others badly damaged. The disaster claimed the lives of 126 people, as well as inflicting countless injuries.

The accidental explosion is the worst disaster of the kind to have occurred in Ireland. In the long run, however, the disaster provided the impetus for the rapid expansion of Dublin in the early 17th Century and beyond, with the rebuilding efforts laying the foundation of the new city centre.

The Explosion of March 11
In the early afternoon on the Friday of 11 March, a consignment of gunpowder barrels was being unloaded by crane from a lighter moored at the dock. Shortly after one O'clock, as the wooden crane was shifting four barrels of gunpowder towards the quay, catastrophe struck. 140 barrels of gunpowder that had been resting on the river side were engulfed by a massive explosion, transforming a tranquil spring day by the riverside into a scene of devastation. The crane and crane house, which were sited by the barrels, were torn asunder, but the force of the blast was felt far across the city. Nearby, many houses owned by Merchant families facing the river Liffey were consumed by the blast, some of them collapsing, others badly defaced. Such was the force of the blast that some buildings in the suburbs of the city were damaged as debris rained down across Dublin. Unsurprisingly, the dozens of riverside labourers who were unlucky enough to be working in the area had no chance of survival: body parts were found scattered hundreds of yards from the crater left by the explosion.

The contemporaneous Gaelic chronicle known as the Annals of the Four Masters describes the disaster:


 * ...a spark of fire got into the powder; but from whence that spark proceeded, whether from the heavens or from the earth
 * beneath, is not known; howbeit, the barrels burst into one blazing flame and rapid conflagration, which raised into the air, from
 * their solid foundations and supporting posts, the stone mansions and wooden houses of the street, so that the long beam, the
 * enormous stone, and the man in his corporal shape, were sent whirling into the air over the town by the explosion of this
 * powerful powder; and it is impossible to enumerate, reckon, or describe the number of honourable persons, of tradesmen of every
 * class, of women and maidens, and of the sons of gentlemen, who had come from all parts of Ireland to be educated in the city,
 * that were destroyed.

The Lead up to Disaster
The disaster took place against the backdrop of the Nine Years' War, in which the powerful Ulster leader Hugh O'Neill and his allies were engaged in an armed challenge to the English Crown. Vast quantities of gunpowder were required to supply the English army in Ireland. The main destination for the cargo of gunpowder was Dublin, the principal city of Ireland. These were offloaded by English ships onto boats waiting offshore: from there, they were ferried across the shallow water to the city.

In the days before the disaster, a dispute had arisen between the Dublin porters and the castle officials. A crown official by the name of John Allen, the Clark of the storehouse, had threatened and intimidated a number of the porters, forcing them to work without pay. As such, many of the porters were effectively on strike, refusing to help unload the barrels of gunpowder. This led to a build up of gunpowder on the quays. This series of events set into motion the disaster which was to follow.

Exactly what triggered the conflagration of the barrels was never determined, although the day of the explosion was noted as unusually dry. Given the circumstances, an accidental ignition in one of the barrels was not at all improbable.

The Aftermath: Dublin Rebuilt
The disaster claimed 126 lives, both men and women, and mostly locals. At the time, the population of Dublin was not quite 10,000, so the impact of the death toll was significant, representing over 1% of the population of the city.

Although the immediate impact of the disaster was horrific, the rebuilding that took place in the early 17th century paved the way for the dramatic expansion of Dublin in the 1600s. In contrast to the timber that was widely employed in Ireland in the Medieval and Tudor era, Much of the new building was in brick. The rebuilding effort also spilled into newly reclaimed land in the east of the city. This facilitated the dramatic growth of the population of the city, from less than 10,000 in 1600 to around 20,000 by the 1630s.

The rebuilding effort was in some respects comparable to that which took place in London after the Great Fire of 1666, transforming Dublin from the style of a Medieval city into that of a more modern city.
