The cathedral's foundation stone was laid on the Feast of the Assumption in 1868.
It is built on the site of the first Catholic chapel in Australia.
The spires, which reach 75 meters in height, were only completed in 2000 to celebrate the millennium.
The crypt's floor design is the work of Australian artist Father Renato Bartolo.
The bell tower contains a peal of 14 bells, which were cast at the Whitechapel Bell Foundry in London.
The cathedral serves as the final resting place for several prominent Australian archbishops.
During construction, workers used a local sandstone that is known for its high iron content, causing the exterior to darken over time.
The building's floor plan is in the shape of a Latin cross.
St Mary's Cathedral serves as the seat of the Archbishop of Sydney and is the mother church of Australian Catholicism. Construction began in 1868 following a fire that destroyed the original 1821 structure, with the main body completed in 1882. The building features a classic Gothic Revival cruciform design inspired by Lincoln Cathedral in England. Its facade is constructed from locally quarried Sydney sandstone. The cathedral houses a notable crypt with a terrazzo floor depicting the creation story. It features extensive stained glass windows produced in Birmingham, England, throughout the 19th and 20th centuries. The cathedral spires were not added until 2000, finally fulfilling the original design vision. It serves as an active parish and a significant venue for civic and religious ceremonies.
