The London Beer Flood occurred on October 17, 1814 in the London parish of St. Giles in the United Kingdom. At the Meux and Company Brewery on Tottenham Court Road, a huge vat containing over 135,000 imperial gallons (610,000 L) of beer ruptured, causing other vats in the same building to succumb in a domino effect. As a result, more than 323,000 imperial gallons (1,470,000 L) of beer burst out and gushed into the streets. The wave of beer destroyed two homes and crumbled the wall of the Tavistock Arms Pub, trapping teenaged employee Eleanor Cooper under the rubble.
The brewery was located among the poor houses and tenements of the St Giles Rookery, where whole families lived in basement rooms that quickly filled with beer. Eight people drowned in the flood, and one person died from alcohol poisoning the next day.
The brewery was demolished in 1922, and today, the Dominion Theatre occupies a part of the site of the former brewery.
