In 1659, the famous mapmaker Joan Blaeu published his world atlas Tooneel des Aardrycks [Display of the Realm of Earth]. The archives in Leiden have made their atlas available online.
This week we are looking at Blaeu’s map of the province of Groningen. It shows its largest city as the same-named Groningen (“Gronningen” on the map), connected to the North Sea by the Reitdiep. The map shows the roads and rivers that connected the smaller towns. See the research guide for Groningen for more information.
