Pyrmont Post Office

Pyrmont Post Office is a two-story building at 148 Harris Street designed in Federation Free Style architecture. The structure displays intricate stone work, grand entry arches, substantial window frames, and a complex hipped roof that define its exterior character.

The building opened in 1852 as a postal sub-office serving the growing industrial district of Pyrmont near the waterfront shipyards. Over time it became a meeting point for the area's working community during a period of rapid industrial expansion.

The name Union Square connects directly to this building, where stonemasons gathered on its veranda in 1855 to establish Australia's first trade union. This link to the labor movement remains central to how locals understand the site.

The building sits on Harris Street, a main thoroughfare through the town center, making it easy to locate and view from the street. Visitors can observe the exterior details from the pavement at any time.

Walter Liberty Vernon designed this building as an exemplar of Federation Free Style architecture featuring exceptionally detailed work. The massive entry arches and complex roof design showcase the craftsmanship of this architectural period.
