1. General Information :

Mannheim with its 327,000 inhabitants is the second-largest city in the state of Baden-Württemberg, Germany, after the capital Stuttgart.
Mannheim is situated at the confluence of the rivers Rhine and Neckar, in the northwestern corner of the state of Baden-Württemberg. The Rhine separates Mannheim from the adjacent Rhineland-Palatinate city of Ludwigshafen. The Hessian border is north of the city. Mannheim is the largest city of the Rhine Neckar Area, a metropolitan area with 2.4 million inhabitants.
Mannheim is unusual among German cities in that its central area is laid out in a grid pattern (called Quadrate, squares), much like many North American cities. The main route through the squares leads to an enormous 18th-century palace. This former seat of the Electors of the Palatinate now houses the University of Mannheim.

Population: 327.000
