Interior of one of the hand hewn convict grain silos.
Seventeen grain silos, to hold wheat, were excavated out of solid rock in the early 1840s, some as large as six metres deep and almost seven metres wide. A guard house and barracks for soldiers followed, along with 12 solitary cells. The fear of food shortages in the colony, born of early difficulties in growing crops and latter difficulties in coming to grips with a climate marked by both irregular rainfall and unexpected periods of drought, saw Governor Gipps concerned about providing emergency supplies for the populace and the military authorities. www.cockatooisland.gov.au/assets/media/about/publications...
