St. Mary's Cathedral near Hyde Park, Sydney, is the spiritual home of the Catholic community in Sydney. It is the seat of the Archbishop of Sydney and is built on the former site of the Catholic Church in Sydney. The cathedral was built from local sandstone, and the "gothic" style is the architectural legacy of the medieval cathedral in Europe. It was built in 1821, and the Catholic priest officially came to Australia in 1820, so St. Mary's Cathedral is also known as the mother of the Australian Catholic Church. The cathedral was destroyed in the fire in 1865. Reconstruction began in 1865 and took more than 60 years to complete in 1928. The minarets of the church were repaired from 1998 to 2000. The cathedral is 107 meters long, the middle hall is 24.3 meters wide, the ceiling is 22.5 meters high, the central tower is 46.3 meters high, and the height of the front tower and the steeple is 74.6 meters. St. Mary's Church is magnificent and solemn. The floor pattern of Father Marogo in the church catacombs is Genesis-themed, inlaid with colored rubble, and is known worldwide for its exquisite handwork. It is not only a precious legacy of the past, but also an important part of the spiritual and cultural life of the entire city and country today.
