Mannheim is located at the confluence of the Rhine and the Neckar in the northwestern corner of Baden-Württemberg. The Rhine separates Mannheim from the city of Ludwigshafen, just to the west of it in Rhineland-Palatinate, and the border of Baden-Württemberg with Hesse is just to the north. Mannheim is downstream along the Neckar from the city of Heidelberg.
Mannheim is unusual among German cities in that its streets and avenues are laid out in a grid pattern, leading to its nickname "die Quadratestadt" ("The City of Squares"). The eighteenth century Mannheim Palace, former home of the Prince-elector of the Palatinate, now houses the University of Mannheim.
According to the Forbes magazine, Mannheim is known for its exceptional inventive power and was ranked 11th among the Top 15 of the most inventive cities worldwide. The New Economy Magazine elected Mannheim under the 20 cities that best represent the world of tomorrow emphasizing Mannheim's positive economic and innovative environment. Since 2014, Mannheim has been a member of the UNESCO Creative Cities Network and holds the title of "UNESCO City of Music". Mannheim is a Smart City; the city's electrical grid is installed with a Power-line communication network.
The city's tourism slogan is "Leben. Im Quadrat." (Life. Squared.). The civic symbol of Mannheim is der Wasserturm, a Romanesque water tower completed in 1886 that rises to 60 metres above the highest point of the art nouveau area Friedrichsplatz. Mannheim is the starting and finishing point of the Bertha Benz Memorial Route.
