In the mid-1660s, Hollar engraved a set of views of towns and cities in northern Europe, which it is believed he drew three decades earlier in person, when he was living in Cologne. The views of Duren and Bonn, specifically, are linked to drawings he made of the cities in 1633 and 1635. All of the views include figures walking around the area, often carrying heavy loads. The focus, however, is clearly on the natural geography of the landscape, as well as the impressive buildings constructed there, including churches, castles, windmills and city walls. The views are:
