The former Van Nelle Factory (Dutch: Van Nellefabriek) on the Schie river in Rotterdam, is considered a prime example of the Constructivism. It has been a designated World Heritage Site since 2014. In 2015, the Van Nelle Factory topped the list of The 25 Most Beautiful Factories in the World.

The buildings were designed by architect Leendert van der Vlugt from the Brinkman & Van der Vlugt office in cooperation with civil engineer J.G. Wiebenga, at that time a specialist for constructions in reinforced concrete, and built between 1925 and 1931.

In the 20th century it was a factory, processing coffee, tea and tobacco and later on additional chewing gum, cigarettes, instant pudding and rice. The operation stopped in 1996. Currently it houses a wide variety of new media and design companies and is known as the Van Nelle Design Factory ("Van Nelle Ontwerpfabriek" in Dutch). Some of the areas are used for meetings, conventions and events.
