Over 30 years ago Mr. Dieter Duncker established ‘Antiquariaat Plantijn’, after having purchased an incomplete 18th century book with decorative engravings of Louis XIV on the battlefields.

In 2001 the decision was made to establish a shop with a storefront and an extensive and divers collection. Residing not too far from one of the major cities in the south, the choice of location was not too difficult and a suitable shop was found in the city of Breda.
