The 18th century was Schiedam's Golden Age, when the gin industry flourished. The standstill drink imports from France made the emergence of the Schiedamse distillery possible. From dozens of distilleries Schiedam jenever was exported throughout the world. The gin industry gave the city its nickname 'Black Nazareth'. This industry is now largely gone. Five windmills in the town, called "De Noord", "Walvisch", "Drie Koornbloemen", "Nieuwe Palmboom" and "Vrijheid" − are the highest traditional style windmills in the world because they had to stick out above the high warehouses, and many storehouses are relics of this past. In one of the former factories at the Lange Haven the National Jenever Museum is established.
