The ten golden castles represent both the urban landscape of Greater Manchester, and its division in to its ten metropolitan districts: Bolton, Bury, Manchester, Oldham, Rochdale, Tameside, Trafford, Salford, Stockport, and Wigan. The red ground represents manpower and the region's red-brick architectural heritage, both legacies of Greater Manchester's industrial past. The embattled border represents the unity and shared future of the region, and its bold, vigilant and forward-looking character.
