Postcard showing Mont Orgueil Castle in Jersey. Construction of the castle began in 1204 and it continued to be used as a fortification until the invention of gunpowder made it obsolete. Walter Raleigh, of privateer fame and Governor of Jersey in 1600, rejected a plan to demolish the castle and recycle the stone for new fortifications, saying "twere pity to cast it down". It was then variously used as a prison and military barracks until it was turned into a museum in 1923.
