The station opened in 1975, along with the other stations of the section of L3 between Paral·lel and Sants Estació stations. This section was originally operated separately from L3 and known as L3b. The station adopted its current name in 1982 at about the same time that L3b was merged with L3 proper.
Future plans are for L2, which currently terminates one stop down the L3 at Paral·lel station, to be diverted into new platforms at Poble Sec. L2 will then continue to a terminus at Barcelona Airport, and Poble Sec will become an interchange station between L2 and L3.
