Homann’s map of Akershus, Norway

A detailed map of the Akershus region of Norway, centred on Christiania (Oslo) and its surrounding towns, roads, and fortifications. The map presents the administrative and geographic structure of the area within the Danish-Norwegian realm. A particularly striking feature is the large mining vignette at right, depicting a cross-section of a mountain mine and illustrating contemporary engineering and extraction techniques. This detailed scene provides a rare visual insight into early modern mining practices.
