The underground station St. Pauli is a stop of the metro line U3. It is located under the Millerntorplatz in the eponymous district east of the Reeperbahn. Of particular importance is the stop in the arrival and departure traffic at events in the Millerntor Stadium and on the Heiligengeistfeld. The underground station has a 90 meter long central platform in a simple depth. Entrances are located at both platforms. The station is considered barrier-free. The station was planned and built in 1910 by the Berlin architect Johann Emil Schaudt. It was opened on May 25, 1912 as Millerntor station and acted for a good month - until the completion of the Hochbahn ring on June 29, 1912 - as terminus. He has a single-track sweeper north of the platform. The first conversion took place in 1926/27, when the platform was expanded from 67 meters to 90 meters in length. Since then, instead of 4-car trains and 6-car trains can be used, which was at least since the mid-1920s was urgently needed. 1935 was renamed the station of "Millerntor" in "St. Pauli ", as the name of the district was much better known beyond Hamburg. During the Second World War, the train service was often interrupted. The longest and last downtime was from March to September 1945. It was only on March 11, 1946, that the line could be put back into service via jetties to the main station. In the 1960s, the access system was supplemented by ticket machines, the barrier system was later completely removed. An extensive renovation took place in 1979. The only access at the south end was completely redesigned and an escalator installed, the platform hall renovated and the wall tiles renewed. In 1999, there was another conversion, in which also the standing on the platform "stall" of the no longer used station keeper was removed with the clearance facilities and the interlocking for the Kehrgleis. The kiosk on the platform has been enlarged and redesigned. At the northern platform, the second access to Glacischaussee / Heiligengeistfeld was built. The walls behind the tracks were clad with sheet metal panels. During the renovation, an original tiled wall from 1912 was discovered in the lobby, which was renovated and preserved. The old, southern access to the vaulted weather protection roof made of metal and glass and an elevator.
The underground station in St. Pauli is very well frequented to get to the Reeperbahn, Landungsbrücken, Fischmarkt etc. by public transport. If you are not familiar with the area, finding a parking space is not that easy. Really well located and well signposted.
