Mainz is located on the 50th latitude, on the left bank of the river Rhine, opposite the confluence of the Main with the Rhine.
The population in the early 2012 was 200,957, an additional 18,619 people maintain a primary residence elsewhere but have a second home in Mainz.
The city is part of the Rhein Metro area comprising 5.8 million people.
Mainz can easily be reached from Frankfurt International Airport in 25 minutes by commuter railway (Line S8).

Mainz is a river port city as the Rhine which connects with its main tributaries, such as the Neckar, the Main and, later, the Moselle and thereby continental Europe with the Port of Rotterdam and thus the North Sea.
Mainz's history and economy are closely tied to its proximity to the Rhine historically handling much of the region's waterborne cargo.
Today's huge container port hub allowing trimodal transport is located on the North Side of the town.
The river also provides another positive effect, moderating Mainz's climate; making waterfront neighborhoods slightly warmer in winter and cooler in summer.

After the last ice age, sand dunes were deposited in the Rhine valley at what was to become the western edge of the city.
The Mainz Sand Dunes area is now a nature reserve with a unique landscape and rare steppe vegetation for this area.

While the Mainz legion camp was founded in 13/12 BC on the Kästrich hill, the associated vici and canabae (civilian settlements) were erected in the direction of the Rhine.
Historical sources and archaeological findings both prove the importance of the military and civilian Mogontiacum as a port city on the Rhine.
