Mariager Abbey was founded in 1430 on a hill overlooking the ferry across Mariager Fjord by the Bridgettines, the last monastic order to reach Denmark before the Reformation, on land acquired in the late 1420s from the dissolved Randers Abbey. Tradition has it that the abbey was founded by several noble families in Eastern Jutland. Sources disagree on whether the abbey was founded from Maribo Abbey or from the Bridgettine mother house, Vadstena Abbey in Sweden.
