Geography of Mainz

Mainz is located on the west bank of the river Rhine, opposite the confluence of the Main with the Rhine. The 2007 population was 200,234; an additional 18,619 people maintain a primary residence elsewhere but have a second home in Mainz and it is also apart of the Rhein Metro area consisting of 5.8 million people. Mainz is easily reached from Frankfurt International Airport in 25 minutes by commuter railway (Rhine-Main S-Bahn).
The city consists of 15 districts: Altstadt, Neustadt, Mombach, Gonsenheim, Hartenberg-Münchfeld, Oberstadt, Bretzenheim, Finthen, Drais, Lerchenberg, Marienborn, Hechtsheim, Ebersheim, Weisenau, and Laubenheim. Until 1945, the districts of Bischofsheim (now an independent town), Ginsheim-Gustavsburg (which together are an independent town) belonged to Mainz. The former suburbs Amöneburg, Kastel, and Kostheim—in short AKK—now are administrated by the city of Wiesbaden (on the north bank of the river). The AKK was separated from Mainz when the Rhine was designated the boundary between the French occupation zone (the later state of Rhineland-Palatinate) and the US occupation zone (Hesse) in 1945.
