Waypoint introductions and full write-ups
1. Group shelter type P
Concrete has a way of outlasting the fear that poured it. Type P group shelters belong to the Dutch defences of the late 1930s, small low bunkers designed to give a section of soldiers somewhere to sit out shelling while they waited for an attack. This one is on the eastern fringe of Utrecht, beside the university quarter of De Uithof, in a belt of land that was meant to be flooded rather than fought over.

Group shelter type P is where the day begins. Next is Corbulo's canal | Vlietwijk.
2. Corbulo's canal | Vlietwijk
The Vliet, a calm green waterway running between Leiden and The Hague, looks like any other Dutch canal, lined with reeds, cyclists and the occasional houseboat. But it follows, more or less, the route of one of the oldest canals in Western Europe. In about AD 47, the Roman general Gnaeus Domitius Corbulo ordered his soldiers to dig a canal linking the Rhine and the Meuse estuaries, so that boats could move supplies along the coast without risking the North Sea. The historian Tacitus says Corbulo did it partly to keep his troops busy. Traces of the Fossa Corbulonis have been found here at Vlietwijk, near Voorschoten, and the site is part of the Lower German Limes World Heritage Site, inscribed in 2021.

3. 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.
