Plaça del Centre is a station of the Barcelona Metro, served by L3 (green line). It takes its name from a square located in the border between two districts of Barcelona: Les Corts and Sants-Montjuïc, and in the intersection of the streets Avinguda de Madrid, Carrer de Berlin, Carrer dels Comtes de Bell-lloc and Carrer de Vallespir, a short walk away from the major railway station Estació de Sants. It was opened in 1975 as part of the line then known as IIIB under the Spanish-language name Plaza del Centro. In 1982 the lines III and IIIB rejoined as a single train service and the name was adapted to its current Catalan language form. The station's platforms are 94 m. long.
