St. Bernard's Abbey in Hemiksem stands at the confluence of the Schelde and Vliet rivers as a remarkable testament to Belgium's religious and military heritage. Founded in 1237 as a Cistercian monastery, the abbey complex evolved through centuries of transformation, serving successively as a marine hospital, prison, and military storage facility following the French Revolution. The architectural ensemble showcases Baroque and Classical styling across its 17th–18th century wings, including the distinctive west wing, sacristy, and infirmary buildings, with landscape elements like former fishponds, orchards, and tree-lined approaches. Protected as established architectural heritage since 2019 and designated a monument since 1973, the abbey represents an enduring link to Belgium's monastic and institutional past.
