Besides the main town himself, the following villages are component localities of Nörten-Hardenberg:


Hardenberg Castle, first mentioned in 1101, was built by the Electors of Mainz. Their Ministeriales (or Burgmann) were the lords of Rosdorf, who were expelled in 1287, followed by the lords of Thüdinghausen (near Moringen) who took on the name knights of Hardenberg. (They are not to be confounded with a westphalian noble family of Hardenberg Castle near Velbert, extinct in 1450). A branch went to Denmark around 1340, which later became extinct, Anne Hardenberg belonging to it. The family acquired further properties near Nörten-Hardenberg, as well as in other regions of Northern Germany. Since 1409 Hardenberg Castle was split between two family branches. Partly destroyed by a thunderstorm in 1698, the castle was abandoned in 1720 and became a ruin. In 1778 created counts, the Hardenberg family, whose most prominent members were Karl August von Hardenberg, prime minister of Prussia, and the poet Novalis, still owns the estate. Since 1710 the family occupies the nearby manor house. In 1700, they founded the Hardenberg-Wilthen distillery, today Germany's second largest liquor producer.
