Waypoint introductions and full write-ups
1. 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.

Corbulo's canal | Knippolder is where the day begins. Next is Mill Network at Kinderdijk-Elshout.
2. Mill Network at Kinderdijk-Elshout
Nineteen windmills stand in two rows along the canals at Kinderdijk, their sails turning slowly against the wide Dutch sky, and it is one of the most iconic sights in the Netherlands. They were built in the eighteenth century to pump water out of the Alblasserwaard, a low-lying polder between the rivers Lek and Noord, which would otherwise be flooded. Each mill lifted water from a lower canal to a higher one, and from there it was let out into the river. Over time steam, diesel and electric pumping stations took over the job, and the most recent ones still keep the polder dry today. The mill network was listed by UNESCO in 1997.

3. Utrecht-Limes road | Zandweg
Two thousand years ago the Rhine marked the northern edge of the Roman Empire here, and along its southern bank the army built a chain of forts, watchtowers and a road to link them. In the western suburbs of Utrecht, in the new district of Leidsche Rijn and the old village of De Meern, that road has been found again under the fields, a gravel and clay embankment with ditches either side, and part of it can be traced along the street called Zandweg. Nearby, at Castellum Hoge Woerd, the outline of a Roman fort has been rebuilt in a modern form, with a museum, a theatre and an observatory, and a flat-bottomed Roman river barge, found here in 1997 almost intact and complete with the cargo and personal belongings of its skipper, is on display. The Lower German Limes became a World Heritage site in 2021.

about 99 km into the recorded legs you reach Utrecht-Limes road | Zandweg. Next is Works along the IJ before Diemerdam.
4. Works along the IJ before Diemerdam
Just east of Amsterdam, where the city's suburbs give way to water and polders, a narrow strip of land runs out along the old shore of the IJ and the IJmeer toward Muiden. The Diemerdam is an old dike, and the works along the IJ before it are part of the Dutch Water Defence Lines, the system of forts, dikes, sluices and inundation fields that the Dutch built over centuries to defend their cities by flooding the land around them. The Defence Line of Amsterdam, a ring of forts around the capital, was listed by UNESCO in 1996 and later joined with the New Dutch Waterline into a single site.

Planning note
Works along the IJ before Diemerdam, about halfway. Next is Dutch Water Defence Lines.
5. 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.
