Dendrochronology placed the tree it came from somewhere between 1089 and 1103 - cut in the era when William II of England was king and the First Crusade was being preached at Clermont. That timber held up the bridge that carried lords across the moat of Zaamslag Castle. The castle is mostly gone now. The artificial hill it stood on - the motte, the locals call it Torenberg - still rises 3.3 meters above the Dutch ordnance datum in the heart of a quiet village on Zeelandic Flanders.

By the second half of the 13th century the lords of Zaam...

The strategic logic was cold and effective: flood the land, deny it to the Spanish, control the Scheldt. The village and castle, both built above the ordnance datum, survived the immediate...

When a 1983 storm wrecked the farm buildings on the outer bailey, Terneuzen municipality used the chance to build houses on top of the castle's archaeology. The Rijksdienst voor het Oudheidk...
