At the end of the 19th century the Imperial Continental Gas Association (ICGA) built two coal gas factory complexes in Amsterdam. By the time the factory shut down, the site was heavily polluted, making it difficult to find a new purpose for the area. In 1992, the buildings were used temporarily for creative and cultural activities and now the Westergasfabriek and the surrounding park are an asset for the whole community. Creative entrepreneurs work in the renovated historic buildings and many high-profile events and festivals are held here. The Westergasfabriek is regarded as a model for redevelopment for other cities far beyond the borders of the Netherlands.
