Grands Boulevards is a station on lines 8 and 9 of the Paris Métro. The section of lines 8 and 9 from just east of Richelieu - Drouot to west of République was built under the Grand Boulevards, which replaced the Louis XIII wall and is in soft ground, which was once the course of the Seine. The lines are built on two levels, with line 8 on the higher level and line 9 in the lower level. The platforms are at the sides and the box containing the lines and supporting the road above is strengthened by a central wall between the tracks. There is no interconnection between the lines at Grands Boulevards, with each level having different accesses to the street.
The station was opened on 5 May 1931 with the extension of line 8 from Richelieu - Drouot to Porte de Charenton. The line 9 platforms were opened on 10 December 1933 with the extension of the line from Richelieu - Drouot to Porte de Montreuil. Until 1998 the station was called Rue Montmartre. It was renamed to reflect the programme of the former Mayor of Paris, Jean Tiberi, to upgrade the main Boulevards of Paris and because the old name suggested that the station was in the Montmartre district, misleading tourists.
