With a population of more than 300,000 made up of people from over 160 different nations, Mannheim is not only the second largest city in Baden-Württemberg: it is also wonderfully diverse, lively and colourful. A big city, a metropolis in which you can feel at home, characterised on the one hand by unpretentious authenticity and on the other by multiculturalism. With 17 city districts – the majority of which are located close to the water – and a city centre laid out in a grid of squares, Mannheim is the metropolitan region’s most important city.
