Disused Barcelona Metro stations

There are a number of disused stations in the Barcelona Metro network, abandoned for various reasons. This is a comprehensive list:

Disappeared

Bordeta - L1 - Opened in 1926, it was closed in 1983 because it was deemed unnecessary as it was close to Santa Eulàlia.
Fernando - L3 - Belongs to a section of the line which was closed when L4 expanded into the area and L3 started growing in another direction. It was replaced by Jaume I.
Correos - L3 - The best known among the disused metro stations in the city, it was part of the aforementioned former L3 section.

Gaudí - L5 - it was next to Sagrada Família and was an early project for Sagrada Família metro station. It can be seen at times from the carriage at the station, when there's enough lighting.
Travessera - L3 - Located between Diagonal and Fontana, around Travessera de Gràcia, it was devised and built as a midpoint between these two stations, which were deemed to be too far from each other, but was never inaugurated.
Banco or Banc - L3 - It was built in 1911 in the area known nowadays as Plaça d'Antonio Maura, the seat of the headquarters of a few banks, but was never opened to public use. In 1925 it became the line's depot, and it may have also been used by the banking institutions.

All these are still in use, but have been moved somewhere around their original location.
