The Williamstown Town Hall was constructed for the Williamstown City Council in two stages 1918 -1919 – front offices section (also referred to as the Municipal Chambers in press of the day)  and 1926 -1927, the detached rear town hall, supper room and facilities.

By 1924 Councillor Henderson had collected a further 25 photographs of local men killed in the war. To display the 265 photographs, the Council contracted the well-known Melbourne firm H Goldman Manufacturing Co. to build a blackwood cabinet with doors designed to keep out the light.

Today the honour board hangs in the Town Hall Ballroom foyer and is considered one of the most important fittings in the building.

The front building itself is significant as representative of conservative classical design and is one of, if not the largest 1910 municipal offices buildings in Victoria.

Today the building is considered a fine example of Greek Revival architectural style and one of the finest and largest interwar period town halls in Victoria.
