The town's name is a fossil of geography. Zwijndrecht comes from the old Germanic words swina drifti - two synonyms, both meaning creek - stacked together for emphasis in a landscape that was almost nothing but water. The suffix -drecht repeats across the map north of the Scheldt, marking every place where streams once braided through marsh and woodland. People settled here only when they learned to build dikes. They raised paths above the wetlands, organized common fields into kouters, and by the fourteenth century had stitched the river's edge into polders. The land you see today, neat and rectilinear from the air, was hand-made over eight centuries from a place that started out under shallow water.

Few places have changed hands more reluctantly. The Count of Flanders granted Zwijndrecht to the van Kets family in 1281, and from there the manorial rights cartwheeled through bankruptcies, wars, and inheritances for half a millennium. The Count of Horne sold the title to a consortium of four Flemish cities to pay debts. The Eighty Years War wrecked the dikes, and a loan default handed the lordship to a creditor named Jan van Hove. An Italian businessman bought it at auction and split it between two sons. A Spanish-controlled financier purchased it on Antwerp's Vrijdagmarkt in 1699. The last lord-by-inheritance, Louis Charles Joseph de Heuvel, was suing his own father for the title when the French Revolution made the whole question vanish. He ended his life as a vagabond in a French prison.

Twice in the twentieth century the Scheldt became the front line. In October 1914 Belgium fell, and Zwijndrecht's forts emptied of defenders while the town filled with hunger, forced labor deportations, and the constant grief of news from the front. Three local men, Jan Baptist Wathy and the brothers Jozef and Frans Van Gaever, were already on a German ship when an Allied torpedo found it - they died on their way to a labor camp, prisoners of one army drowned by the other. Then came 1940, the Swastika over the Antwerp Cathedral, and a street battle in May that killed sixteen Germans, twenty-nine Belgians, and thirty-two civilians who had nowhere to go. The last act was the cruellest. After the British liberated Antwerp in 1944, the Germans tried to strangle the port with V-1 and V-2 rockets - and most of them missed. Seventy-six fell on Zwijndrecht and Burcht between October and March. Thirty-three civilians died from weapons aimed at a harbor they could not see.

The 3M factory looks like any other industrial complex along the Scheldt - tanks, pipes, the low hum of process equipment. From 1976 to 2002 it produced perfluorooctanesulfonic acid, a forever chemical used in stain-resistant coatings and firefighting foams. PFOS does not break down. It accumulates in soil, in water, in blood. Belgian regulators learned of internal contamination data in 2017 and said little. The public learned in 2021, after construction crews on the Oosterweel Link began moving polluted earth. By then the chickens of Zwijndrecht had been eating it for a generation. Residents were told to stop consuming their own eggs, to throw away garden vegetables, to limit fish from the river. The investigation that followed turned into a parliamentary scandal. The factory operates still. The chemicals it left behind will outlast everyone reading this.

Walk through Zwijndrecht today and the contamination is invisible. The Heilig Kruiskerk's twelfth-century stones stand in the same spot they always have. The town hall, built in the 1930s, faces a quiet square. Down by the harbor, container cranes work the same waterline that once carried Roman vessels and Spanish galleons. Two-time Olympic fencing champion Paul Anspach was born here in 1882. So was Leo Tindemans, who would serve as Prime Minister of Belgium. On January 1, 2025, Zwijndrecht ceased to exist as a separate municipality - it fused with Beveren and Kruibeke into a new entity, crossing back into East Flanders after a century in Antwerp Province. The map changed. The river kept moving. The chemicals kept seeping.
