The seat of the Roman Catholic Archdiocese of Perth, this cathedral stands at Victoria Square after more than a century of construction and renewal.
At a glance
St Mary’s Cathedral, officially the Cathedral of the Immaculate Conception of the Blessed Virgin Mary, dominates Victoria Square at the northern end of Victoria Avenue. It serves as the cathedral church and residence of the Archbishop of Perth, currently Timothy Costelloe.
History
The cathedral was built across three distinct phases. The first phase was completed in 1865, establishing the original structure. During the 1920s, architects drew up ambitious plans for a replacement—a larger Perpendicular Gothic edifice intended to supersede the existing cathedral. Construction began but halted abruptly with the Great Depression, leaving the work incomplete. For seven decades, the cathedral remained partially constructed, with sections deteriorating and requiring urgent repair. In the late 1990s and early 2000s, fundraising efforts succeeded in reviving the expansion project. A new curved design replaced the original Perpendicular Gothic plan, featuring a second spire and an underground parish centre. After closure in 2006 for major construction work, the cathedral reopened in December 2009.
What you see
The cathedral’s architectural narrative is written in its hybrid fabric. The 1865 structure forms the core; the expanded sections added in the early 2000s introduce contemporary curved forms and a second spire. The recent additions include an underground parish centre, integrating modern convenience with the heritage structure above ground.
Cultural significance
St Mary’s represents Perth’s Catholic heritage and institutional continuity. Its protracted construction—from 1865 through interruption to modern completion—mirrors broader Australian cultural and economic history, from colonial establishment through depression and post-war prosperity.
