Bunnik ( pronunciation ) is a municipality and a village in the Netherlands, in the province of Utrecht. The recorded history of the village dates back nearly 2000 years, when the Romans constructed a fort at Fectio (now Vechten) with a harbour facing the river Rhine, which marked the border of the Roman Empire. The fort developed into a thriving trading centre, which continued to exist after the Romans abandoned the fort in the fourth century. Subsequently, the area was occupied by the Frisians and the Franks.
