One of the main churches in Naples, it's at the west side of Piazza del Plebiscito, the city's main square. The place was planned by King Joachim Murat of Naples (Napoleon's brother-in-law) as a tribute to the emperor. When Napoleon was dispatched, Ferdinand I of Bourbon continued the construction but converted the final product into the church one sees today. The church is reminiscent of the Pantheon in Rome. The façade is fronted by a portico resting on six columns and two Ionic pillars. Inside, the church is circular with two side chapels. The dome is 53 metres high.
