Fort Sint-Marie

Fort Sint-Marie sits on the left bank of the Scheldt River with six bastions arranged in a star shape designed for naval defense. The structure holds multiple casemates, gun positions, and military quarters inside its walls.

The current fort was built in 1865 as part of Belgium's national defense plan and replaced an earlier structure from 1584 that defended Antwerp during Spanish rule. This rebuilding reflected the military needs of the newly formed Belgian state.

The fort's name comes from Mary, reflecting the religious devotion of Alexander Farnese, who ordered the original fortification in the 16th century. You can still sense this spiritual purpose today when walking through the site.

Visiting requires careful attention when navigating multiple levels and tight passageways between the casemates. Sturdy shoes are recommended since the grounds are uneven with varying surface conditions.

In 1881 the fort received Belgium's only torpedo installation, marking its role as a key site in the country's coastal defense during industrial expansion. This made it one of the most advanced military positions of its time in the region.
