Input: Question: Which of the actual locations for which replica sets were built on the same backlot for Angels and Demons was constructed first?  Passage: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.
