We pass this enormous canal,dug in the 70's as another route for commercial traffic into France. Due to silting on the French side (so the Belgians say), it has been closed for years. The locks are still manned everyday but nothing is allowed through!
It transpires that this canal used the same route as an ancient Roman canal long since filled in. The resulting finds as the new canal was excavated are exhibited in the town of Ath and include three Roman wooden barges, almost completely preserved.
