In October 1966 construction was started, finishing in October 1971 as part of the new S-Bahn network for the 1972 Summer Olympics. Until early 2003 there were almost no further refurbishments done at the station. From 2003 to 2006, the platforms of the U-Bahn were widened to expand passenger capacity and were lifted by 4 cm to secure same-level boarding.
The increase in traffic and the new Allianz Arena also required a larger capacity of this already overcrowded pivotal transfer station. New pedestrian tunnels were built, which provide more room for passengers transferring from and to the S-Bahn. They lie parallel to the existing platforms and are connected to them by 11 portals. At the south end, they meet the transverse tunnel, where the escalators to the S-Bahn platforms are located.
Under the Zweite Stammstrecke ("Second main line") tunnel project, Marienplatz station is to be connected to a second station further north, Marienhof, via the enlarged subway access tunnels on the fourth level.
Parts the music video for Four Out of Five by the Arctic Monkeys features the station as Alex Turner walks down a tunnel called the U-Bahn.
