St Mary's Cathedral, Sydney
St Mary's has the greatest length of any church in Australia (although it is neither the tallest nor largest overall). It is located on College Street near the eastern border of the Sydney central business district in the City of Sydney local government area of New South Wales, Australia. Despite the high-rise development of the central business district, the cathedral's imposing structure and twin spires make it a landmark from every direction. In 2008, St Mary's Cathedral became the focus of World Youth Day 2008 and was visited by Pope Benedict XVI who consecrated the new forward altar. The cathedral was designed by William Wardell and built from 1866 to 1928. It is also known as St. Mary's Catholic Cathedral and Chapter House, Saint Mary's Cathedral and St Marys Cathedral. The property was added to the New South Wales State Heritage Register on 3 September 2004.
