One of the main objects in the Liberna Collection is the Topographical Atlas – an extensive collection of loose and bound topographical maps of the Netherlands. It includes maps in many different scales: from individual building plans and city and garden plans to military maps such as Jacques Callot’s Siege of Breda. A highlight of this collection is the oldest map of Amsterdam, produced in 1544 by Cornelis Anthoniszoon (ca. 1505–1553). This impressive map is printed with twelve different woodblocks and measures more than 100 x 100 cm. It shows Amsterdam from a bird’s eye view, i.e. (obliquely) from above. The city is still surrounded by its medieval city wall. Although Amsterdam expanded enormously in the following centuries, much can be seen that still exists even today. Thus the Singel (then a medieval moat) and the Oude Kerk (Old Church) and Nieuwe Kerk (New Church), for example, were already part of the cityscape in the 16th century.
