Input: Question: Who designed the actual building for which a police station in Rome opposite it was used for the exterior? Passage 1:Orion, named after the mythological hunter, Orion, was the fourth ship of her name to serve in the Royal Navy (RN). The ship was laid down at HM Dockyard, Portsmouth on 29 November 1909. She was launched on 20 August 1910, and was commissioned on 2 January 1912. Including her armament, her cost is variously quoted at £1,855,917 or £1,918,773. Orion was assigned to the 2nd division of the Home Fleet as the flagship of Rear-Admiral Sir Herbert King-Hall, the division's second-in-command. The ship was slightly damaged on 7 January when the pre-dreadnought battleship broke loose from her moorings and collided with Orions bow. The division was redesignated as the 2nd Battle Squadron (BS) on 1 May. The ship, together with her sister ships and , participated in the Parliamentary Naval Review on 9 July at Spithead. They then participated in training manoeuvres. King-Hall was relieved by Rear-Admiral Rosslyn Wemyss on 29 October. On 13 November, the ship participated in comparative gunnery trials with Thunderer to evaluate the effectiveness of the latter's gunnery director. Thunderer decisively outshot Orion, although some of her success was because her director was above the smoke that obscured the target from Orions guns. The test was repeated in better conditions on 4 December and Orion performed much better, apparently beating Thunderer. The three sisters were present with the 2nd BS to receive the President of France, Raymond Poincaré, at Spithead on 24 June 1913 and then participated in the annual fleet manoeuvres in August. Wemyss was relieved in his turn by Rear-Admiral Sir Robert Arbuthnot, 4th Baronet on 28 October. Captain Frederic Dreyer assumed command of Orion that same day. On 4 November, Orion, Thunderer, the dreadnought and the predreadnought fired at and sank the target ship to give their crews experience in firing live ammunition against a real ship.
 Passage 2:The son of Thomas Butler, 6th Earl of Ossory and his wife Emilia (née van Nassau-Beverweerd), and grandson of James Butler, 1st Duke of Ormonde, Butler was born in Dublin and was educated in France and afterwards at Christ Church, Oxford. On the death of his father on 30 July 1680 he became Baron Butler in the English peerage and Earl of Ossory by courtesy. He obtained command of a cavalry regiment in Ireland in 1683, and having received an appointment at court on the accession of James II, he served against the Duke of Monmouth at the Battle of Sedgemoor in July 1685. Having succeeded his grandfather as Duke of Ormonde on 21 July 1688, he was appointed a Knight of the Order of the Garter on 28 September 1688. In 1688 he also became Chancellor of Trinity College, Dublin and Chancellor of the University of Oxford.
 Passage 3:The Saint Peter's Square and the Piazza Navona sets were built on the same backlot; after completion of scenes at the former, six weeks were spent converting the set, knocking down the Basilica side and excavating of tarmac to build the fountain. As there had been filming at the real Piazza Navona, the transition between it and the replica had to be seamless. To present the Santa Maria del Popolo undergoing renovation, a police station in Rome opposite the real church was used for the exterior; the scaffolding would hide that it was not the church. Cameron built the interior of Santa Maria del Popolo on the same set as the recreated Santa Maria della Vittoria to save money; the scaffolding also disguised this. The film's version of Santa Maria della Vittoria was larger than the real one, so it would accommodate the cranes used to film the scene. To film the Pantheon's interior, two aediculae and the tomb of Raphael were rebuilt to scale at a height of , while the rest was greenscreen. Because of the building's symmetrical layout, the filmmakers were able to shoot the whole scene over two days and redress the real side to pretend it was another. The second unit took photographs of the Large Hadron Collider and pasted these in scenes set at CERN.
