Brielle Fortress
Description
In 1572, during the Eighty Year War with the Spaniards, Sea Beggars (Calvinist Dutch nobles) captured Brielle. After this work began on replacing the Medieval town walls with a modern fortress. This process of modernisation and replacement continued until 1713. The fortress ring has nine bastions and five ravelins and was designed by the fortress builders Willem Paen and Menno van Coehoorn. Since 1713 there have been few changes to the fortress, so the defences are some of the most important fortifications remaining in the Netherlands. It is possible to walk all the way around the walls to view them. Besides the walls there are also various buildings in the town centre which once had a military function, such as the Arsenaal, the Infirmerie and the Hoofdwacht (main guardhouse).
