The cathedral's original foundation stone was laid in 1863, but construction was delayed for decades due to severe financial constraints and local labor shortages.
The 2009 expansion project was the first major structural update to the cathedral since the 1930s.
The cathedral is constructed from a combination of local limestone and granite sourced from the Darling Range.
During the 2009 renovation, workers discovered a time capsule from the original 19th-century construction period embedded in the foundations.
The cathedral is officially recognized by the Heritage Council of Western Australia for its historical and social significance to the state.
Saint Mary's Cathedral stands as the principal church of the Roman Catholic Archdiocese of Perth, situated on the prominent Victoria Square. The structure represents a unique architectural fusion, combining the original 1865 Victorian Gothic nave with a substantial 2009 expansion and refurbishment. The recent modernization added a secondary spire and a crypt, significantly increasing the building's seating capacity. The design integrates local Western Australian stone, reflecting the regional geology within the ecclesiastical space. It functions as an active liturgical center hosting major diocesan ceremonies and daily services. The site sits on the highest point in the city of Perth, overlooking the central business district. Its interior features a contemporary sanctuary layout contrasted against the preserved 19th-century structural elements.
