Kultur- und Stadthistorisches Museum by Sjalen
The city's history museum pulled us in because of its star attraction: the maps and globes of famous cartographer Mercator. Born in what is today Belgium, Mercator moved to Duisburg early on as it was more tolerant and allowed him to produce scientific images of the world without too much questioning by the church. Today the museum shows his two famous globes, one including astrological symbols, as well as plenty of maps. There are also maps by his competitors and followers. Downstairs, the museum shows the history of Duisburg which is more fascinating than you think and every section has at least some text in English so you can read up on the history of Frankish tribes by the Ruhr as well as coal mining. There is also a small but interesting section on Duisburg during WWII. Finally, there are some models of the city throughout time so you can see how it has grown from a small Frankish settlement to a major German city.
