A modern fort and a Roman one stand within a couple of kilometres of each other here, and both exist because of the same river. Vechten, on the Kromme Rijn just east of Utrecht, was the Roman fort of Fectio, one of the best-known sites on the Lower Germanic frontier. It lay at a point where the Rhine split, with the branch that became the Vecht heading north, and that made it a perfect depot. Soldiers, grain, and building stone all went through here, and archaeologists have pulled a remarkable amount out of the ground, including altars, bronze statuettes and the debris of a busy harbour.
The soil explains the finds. Flood clay and river silt sealed everything in wet layers, so wood, leather and metal survived in conditions that would have rotted them elsewhere. The frontier line, the Limes, was inscribed on the World Heritage list in 2021, and Vechten is part of that story. Not much is visible, and part of the appeal is that you must imagine the fort from the shape of the land, a slight rise above the low meadows, with the river curving beside it.
The second fort is Fort bij Vechten, a nineteenth-century brick bastion that belonged to the New Dutch Water Line. Its low earth-covered walls and moat survive and the grounds house a museum about the Water Line, which tells how Dutch engineers planned to hold off invaders by flooding the fields. The coincidence of these two defensive structures, nearly two thousand years apart, on the same river bend makes the area a perfect, quiet lesson in how geography repeats itself.
The riding is mild. The Provincialeweg and the lanes around Bunnik run through flat green country with farms, orchards and the occasional old country house, and on a weekday you will have the roads mostly to yourself apart from cyclists. Weekends bring more people, with families and sporting cyclists out in numbers, and speed limits are low and enforced. A headwind on the open stretches can be tiring, and spring showers pass quickly.
Bunnik has about six thousand people, so fuel and a meal are easy, and Utrecht is a short ride west. A bakery in the village will sell you a sandwich and an apple tart, and the riverside paths are lovely in the soft light of late afternoon.
