The History and Architecture of the Fortified Town of Bergen op Zoom

Since the Middle Ages, Bergen op Zoom has developed at a strategically important location between Brabant, Zeeland and the waterways leading to the Scheldt. Around 1330, work began on constructing city ramparts; towards the end of the 15th century, the fortifications of the town proper were linked to those of the harbour district. With the advent of powerful artillery, the medieval wall gradually evolved into an early modern fortress featuring low, massive earthworks, projecting bastions, moats and ravelins situated in front of the main defences.

This defence proved its worth on several occasions during the Eighty Years’ War. Spanish armies, led by the Duke of Parma in 1588 and by Ambrogio Spinola in 1622, failed to capture the town. The long siege of 1622 in particular reinforced Bergen op Zoom’s reputation as a fortress that was difficult to conquer: the defenders were able to receive supplies via the western waterways, whilst relief forces eventually forced the besiegers to retreat. These successes conferred great military and symbolic importance on the town for the Republic of the United Netherlands.

From 1628 onwards, Bergen op Zoom was incorporated into the West Brabant Water Line. To the north of the town, a chain of forts – including Moermont, Pinssen and De Roovere – was established, along with controllable floodplains. Locks, streams and canals made it possible to flood low-lying areas, whilst the forts blocked the dry approaches along the Brabantse Wal. The defences were thus based not solely on walls, but on the deliberate interplay of architecture, water management and the terrain.

Around 1700, the eminent military architect Menno van Coehoorn He completely redesigned the fortifications. He had the bastions reinforced, the ravelins and lunettes extended, and large sections fitted with dry moats and a system of underground counter-mines. The deeply staggered outer works were intended to force attackers to advance section by section under constant fire. The Ravelijn op den Zoom, constructed in 1703, is the most complete surviving part of this fortification and still conveys an impression of Coehoorn’s ingenious defence system.

However, the myth of its impregnability came to an end during the War of the Austrian Succession. Following a gruelling French siege, Bergen op Zoom fell in September 1747. Although the town returned to Dutch control as early as 1748, military developments gradually diminished the value of the elaborate fortress. In 1867, its status as a fortress was revoked; large sections of the ramparts and outer works were subsequently demolished to make way for urban expansion. Preserved elements such as the Ravelijn op den Zoom, the Waterschans and sections of the West Brabant Water Line nevertheless make Bergen op Zoom an outstanding site commemorating Dutch fortification and hydraulic engineering.
