In addition to 110 kilometres of records, the Nationaal Archief also holds the biggest and most important collection of maps and drawings in the Netherlands. This collection comprises some 300,000 items spread over 100 archives and dating as far back as the late Middle Ages. You can use these maps to research the history of the formation of the Netherlands and its former overseas territories, e.g. a fort abroad, changes to the Dutch coastline or the land owned by a person’s ancestors. The possibilities are endless.
