Wuppertal, Germany

With a population of 358,938, Wuppertal is a dense, industrial city in western Germany. The urban sprawl and steep hills make it a logistical headache, while the city's heavy tax burden and persistent bureaucracy can be a slog for newcomers. However, Wuppertal offers a diverse cultural scene, from the iconic Schwebebahn suspension railway to the Wuppertal Dance Theatre. Overall, this gritty, hardworking city may appeal to those seeking an authentic, no-frills German experience, but it's not for the faint of heart.
