About 238 Castlereagh Street, 1875

238 Castlereagh Street, 1875 is the mapped name of a memorial plaque on Castlereagh Street in central Sydney. OpenStreetMap records the exact point as a plaque and retains that label. The City of Sydney Archives separately catalogues a heritage property file for 238–240 Castlereagh Street, anchoring the marker to the correct address.

Do not interpret 1875 in the plaque’s mapped title as the construction date of the surviving building. A City of Sydney planning report states that the Australian Workers Union building at 238–240 Castlereagh Street was constructed in 1878, originally as Protestant Hall. The Sydney Local Environmental Plan lists the former Workers Building, including its interiors and lightwell, as local heritage item I1705. Those records describe the building and site; they do not transcribe the plaque or explain why its title uses 1875. Treat the marker as a brief exterior stop, not a museum with visitor hours. No plaque-specific admission, opening schedule, accessibility provision or guided-tour programme is recorded.
