Beneath the Old Town
Marienhof station, the central stop on the new line, is being built by Implenia as technical lead in a joint venture with Hochtief. The construction site is located directly under Munich’s old town, behind the city hall (Rathaus) and directly next to the world famous Dallmayr coffee house. The Frauenkirche church is also very close by. The new station is around 40 metres below the surface, deeper than any previous tunnel made beneath Munich city centre. This depth is necessary for two reasons: firstly to protect the surrounding buildings, and secondly because the structures have to pass below the existing U3 and U6 lines. The 210-metre-long platforms will be on the lowest level, beneath an approximately 14-metre-high concourse floor and then a mezzanine floor with entrances and exits to the new S-Bahn station. Passengers will be able to change at Marienhof onto lines U3 and U6.
