Underground Grain Silos
Underground Grain Silos, Historical grain storage system on Cockatoo Island, New South Wales, Australia.
The underground grain silos consist of three complete and two half bottle-shaped chambers carved into sandstone with square mouths for water exclusion.
Colonel George Barney designed these grain storage facilities in 1839, where convict labor groups excavated them to store 20,000 bushels of wheat.
The silos represent early colonial engineering solutions for food storage needs in New South Wales during the nineteenth century development period.
Located 65 meters southeast of Biloela, between the Clerk of Petty Sessions Cottage and the cliff, the silos remain accessible for visitor inspection.
The storage chambers were later repurposed in the 1870s for water containment, with evidence of thirteen original silos still visible on the island.
