prayers in the Roman Missal from the "Mass in times of civil disturbance" for the victims of the 2014 Sydney hostage crisis. A memorial service was held at the cathedral on the morning of 19 December for Tori Johnson and Katrina Dawson, in attendance were the Governor-General Peter Cosgrove, then-Minister of Communications Malcolm Turnbull, Senator Arthur Sinodinos, Premier of New South Wales Mike Baird, and then-Minister of Transport Gladys Berejiklian. Architecture Plan St Mary's Cathedral is unusual among large cathedrals in that, because of its size, the plan of the city around it and the fall of the land, it is oriented in a north–south direction rather than the usual east–west. The liturgical East End is at the north and the West Front is to the south. The plan of the cathedral is a conventional English cathedral plan, cruciform in shape, with a tower over the crossing of the nave and transepts and twin towers at the West Front (in this case, the south). The chancel is square-ended, like the chancels of Lincoln, York and several other English cathedrals. There are three processional doors in the south with additional entrances conveniently placed in the transept facades so that they lead from Hyde Park and from the presbytery buildings and school adjacent the cathedral. Style The architecture is typical of the Gothic Revival of the 19th century, inspired by the journals of the Cambridge Camden Society, the writings of John Ruskin and the architecture of Augustus Welby Pugin. At the time that the foundation stone was laid, the architect Edmund Blacket had just completed Sydney's very much smaller Anglican cathedral in the Perpendicular Gothic style and the Main Building of Sydney University. St Mary's, when William Wardell's plan was realised, was to be a much larger, more imposing and more sombre structure than the smaller St Andrew's and, because of its fortuitous siting, still dominates many views of the city despite the high-rise buildings. The style of the cathedral is Geometric Decorated Gothic, the archaeological antecedent being the ecclesiastical architecture of late 13th century England. It is based fairly closely on the style of Lincoln Cathedral, the tracery of the huge chancel window being almost a replica of that at Lincoln. Exterior The lateral view of the building from Hyde Park is marked by the regular progression of Gothic windows with pointed arches and simple tracery. The upper roofline is finished
