’s-Hertogenbosch

The city is nicknamed 'Swamp Dragon'. The city got this name from its role in the Eighty Years' War. 's-Hertogenbosch was then a fortified city surrounded by swamps such as Het Bossche Broek and the Moerputten, which meant that the city was considered 'impregnable'.
The city is located on four rivers, the Maas, the Aa, the Dommel and the Dieze.

The name Den Bosch is older than the official name 's-Hertogenbosch. That duke was the Duke of Brabant.

The shorter name Den Bosch is widely used, but is not official. This is in contrast to The Hague, which is officially used.

In many other languages, 's-Hertogenbosch is referred to by its translation: Bois-le-Duc in French, Boscoducale in Italian, Bolduque in Spanish and Herzogenbusch in German. The (Neo-)Latin name is Silva Ducis or Buscum Ducis. During carnival time the city is called Oeteldonk.
