barricade: [17] 12 May 1588 was known as la journée des barricades ‘the day of the barricades’, because in the course of disturbances in Paris during the Huguenot wars, large barrels (French barriques) filled with earth, cobblestones, etc were hauled into the street on that day to form barricades – and the term has stuck ever since. Barrique itself was borrowed from Spanish barrica ‘cask’, which was formed from the same stem as that from which English gets barrel [14]. It has been speculated that this was Vulgar Latin *barra ‘bar’, on the basis that barrels are made of ‘bars’ or ‘staves’. => bar, barrel[barricade etymology, barricade origin, 英语词源]
