The National Archives of the Netherlands (Nationaal Archief), which is situated in The Hague, holds over 3.5 million records that have been created by the central government, organisations and individuals and are of national significance. Many records relate to the colonial and trading history of the Netherlands in the period from 1600 to 1975. The Dutch presence in countries in North and South America, Africa and Asia is reflected within these collections. The rich collection consists of 137 km of documents, 15 million photographs and nearly 300,000 historical maps and drawings and 800 terabyte of digital files.
