Portions of Line 2 commenced in the 1950s as line II, now part of Line 5, initially running from La Sagrera-Meridiana station to Vilapicina station. The current L2 was planned in preparation for the 1992 Summer Olympics, to be held on the then-underserved Montjuïc. Delays, however, resulted in an opening dates in 1995, three years after the Games. L2 is the third-newest Metro line in the network, after L11 and the combined L9/L10. All of its stations are underground.
