St Mary’s Cathedral is the cathedral church of the Roman Catholic Archdiocese of Perth. The cathedral as it now stands was constructed in three main phases, with the first phase completed in 1865. Plans were drawn up for the replacement of the cathedral in the 1920s with a larger Perpendicular Gothic edifice. However, construction was interrupted by the onset of the Great Depression. After 70 years incomplete, funds were eventually raised in the late 1990s and early 2000s for the completion of the expansion. This stunning cathedral is in Victoria Square, opposite the Royal Perth Hospital, less than a ten minute walk east of the CBD.
