Waypoint introductions and full write-ups
1. Dutch Water Defence Lines
Forget mountains and passes: the Dutch defended Amsterdam with water. Between the 1880s and the 1920s, the army built a ring of forts around the capital at a distance of roughly fifteen to twenty kilometres, the Stelling van Amsterdam, designed to flood the surrounding polders to a depth too shallow for boats but too deep to wade through. Forty-odd forts, along with dykes, sluices and batteries, formed the ring, and the area north of the city near De Rijp and the Beemster was part of it. The Defence Line of Amsterdam gained World Heritage status in 1996, and in 2021 it was extended to include the older New Dutch Waterline further south, the whole now known as the Dutch Water Defence Lines.

2. Dutch Water Defence Lines
The Dutch had a clever idea for defending their heartland: instead of building walls, they would drown the approaches. The Dutch Water Defence Lines, a World Heritage site, consist of a long belt of land around Amsterdam and Utrecht that could be flooded deliberately in wartime, with water deep enough to stop soldiers on foot and wagons, but too shallow for boats. Forts, dikes, sluices and pumping stations controlled the water. The New Dutch Waterline, built in the nineteenth and early twentieth centuries, ran south-east of Amsterdam through the area around Maarssen and the Loosdrecht lakes, and it was mobilised during the First and Second World Wars, though aircraft and modern artillery had made it largely obsolete by then.

3. Corbulo's canal | Knippolder
In AD 47, a Roman general on a quiet frontier had a problem, which was how to keep his legions from getting restless. Gnaeus Domitius Corbulo, newly appointed to command in Lower Germany, solved it, according to the historian Tacitus, by making his troops dig. The result was a canal, the Fossa Corbulonis, linking the mouth of the Rhine with the Maas, so that ships could pass between the two rivers on a sheltered inland route rather than risk the open North Sea. It is one of the earliest known large engineering works of its kind in the Netherlands.
