The station platforms were established under Rue Auber for line 3; for line 7, under Avenue de l'Opéra; and for line 8, under Boulevard des Capucines; and partially under the Place de l'Opéra. The three lines cross thanks to a common underground structure located under the square. The station is connected by underground passages with the Gare d'Auber and, indirectly with the Havre – Caumartin station, then the Haussmann–Saint-Lazare station and the stations Saint-Lazare and Saint-Augustin.
History
The Line 3 platforms opened on 19 October 1904 as part of the first section of the line opened between Père Lachaise and Villiers. A twenty metre high masonry well was built to avoid the need for heavy underpinning work when Line 7 and Line 8 were planned to be built. This work was affected by groundwater, which required the support of three concrete pillars, made by sinking caissons with workers digging out the mud with compressed air. The work lasted eleven months, from March 1903 to February 1904. It owes its name to the Garnier opera house, built by the architect Charles Garnier. The Line 7 platforms opened on 5 November 1910 as part of the first section of the line opened between Opéra and Porte de la Villette. The Line 8 platforms opened on 13 July 1913 as part of the first section of the line opened between Opéra and Beaugrenelle and then on 30 June 1928 when it was extended to Richelieu - Drouot. From the 1950s to the 1980s, the walls in line 3 were covered with metal bodywork before their renovation in Andreu-Motte style. The platforms of lines 7 and 8 were modernized from the early 1970s to 2007 in a unique style with three shades of blue. The station's name consisted of large raised white capital letters. This decoration, derived from the Mouton-Duvernet style, from which it notably adopted the characteristic lighting canopies, was sometimes nicknamed the swimming pool. The blue ceiling was then repainted in white to increase the brightness. The entire layout was removed in 2007 when the station was renovated as part of the RATP Renouveau du métro program. Only the Saint-Lazare station on lines 12 and 13 had comparable decoration until the mid-2000s. On April 1, 2016, the RATP replaced one of every two nameplates on the platforms of the three lines to make an April Fool for a day, like twelve other stations. Opera is humorously renamed "Apéro" by anagram. In 2019, 10,501,357 travelers entered this station which places it at the 15th position of metro stations for its usage.

Station layout
Platforms
The platforms of the three lines are of standard configuration. Two in number per stopping point, they are separated by the metro tracks located in the center. The platform for line 3 is established flush with the walls. The ceiling consists of a metal roof, whose beams, burgundy in color, are supported by vertical pillars. The decoration is in the Andreu-Motte style with two burgundy light canopies, benches, tympans and walls fitted with large white flat tiles in a stretched sandstone and purple Motte seats. On the other hand, the outlets of the corridors are fitted with standard white bevelled tiles. Advertisements are devoid of frames and the name of the station is written in Parisine font on enameled plates. With Palais Royal - Musée du Louvre on line 1 and Concorde on line 8, this is one of three stations in the Andreu-Motte style to be treated in shades of purple, this shade being part of the lexicon exceptional colors for this decoration. The platforms of lines 7 and 8 have an elliptical vault and are similarly arranged, with a slight extra curve for line 7, while the platforms of line 8 have a higher of the vault. The style is that used for most metro stations. The lighting canopies are white and rounded in the Gaudindu renouveau du métro des années 2000 renovation, and the bevelled white ceramic tiles cover the walls and the tympans. The vault is painted white. The advertising frames are in white ceramic and the name of the station is written in Parisine font on enameled plates. The seats are Akiko style, green for line 7 and orange for line 8. As part of the treatment for major permeation, the lighting canopies for line 7 is temporarily removed.
