Donnybrook stone
Introduction General Post Office in Perth'''Donnybrook stone''' is a fine to medium-grained feldspathic and kaolinitic sandstone found near the town of Donnybrook, Western Australia. It originates from the early Cretaceous (144-132 MYA) and features shale partings and colour variations which range from white to beige and pink.Donnybrook stone is used as dimension stone in the building industry and is both a commercial name as well as a stratigraphic name.Many public and private buildings in Western Australia feature Donnybrook stone. These include the facade and portico to the Parliament House building in West Perth, the General Post Office in Perth, the entry portal to the Fremantle Railway Station and the Police Courts building in Beaufort Street, Perth, the latter of which is constructed entirely of Donnybrook stone.
History Gold was found in Donnybrook in the mid-1890s and was being mined there in late 1898.There was controversy regarding its usage in the early twentieth century.There were up to eight quarries producing Donnybrook stone in and around the town in the 1930s. Most of these have since closed, however, in 1981 the Goldfields Quarry on the Upper Capel Road re-opened and now produces material for floor tiles and facing slabs. Several of the closed quarries are on the Donnybrook-Balingup Road.
