Brielle's ramparts are still intact. The shape was designed by fortress builders Willem Paen and Menno van Coehoorn, who worked for the Staten van Holland (States of Holland).
Few changes have been made to the fortifications since 1713, making Brielle's defences the most important remaining fortifications in the Netherlands. The fortress consists of various bastions, ravelins (triangular fortifications) and gates and lends itself perfectly to be viewed during a walk across the ramparts.
