Ravelijn Op den Zoom is one of the few remnants of Bergen op Zoom's illustrious fortifications. The Berg fortress was an important part of the Zuiderwaterlinie, guarding access from the south to Holland and Zeeland. A visit to this pentagonal island and the casemates is only possible with a guide. Ask at VVV Brabantse Wal for the possibilities.

Important: advance booking is required.
