Sunlight falls in clean geometric shapes across a concrete floor. White ceramic tiles line the walls to shoulder height, their grout darkened with grime. A row of clerestory windows runs the full width of the space, steel trusses spanning beneath a translucent roof. Against the far wall, a bank of olive-green metal lockers stands with doors hanging open. Photographs and notices remain pinned to the tiled partitions between shower alcoves. The room is stripped bare but intact. Portland Cement Works operated from 1929 until its closure in 1991, producing cement from the limestone deposits along the Shoalhaven River near Portland, New South Wales. This wash house served the workforce at shift's end.
