Rijnland
When used in the specific Dutch context, "Rijnland" generally refers to the area around the Oude Rijn, the lower reaches of a minor branch of the Rhine river in the Netherlands. This river is referred to as "Rijn" (Rhine) in the Netherlands for historical reasons. This small, heavily-canalised and remote branch of the Rhine was, in fact, the river that the Romans used to call the Rhine and the northern limit of the Roman Empire in this area. The term "Rijnland" is itself ancient.
