Kalø Castle was founded in 1313 by the Danish king Erik Menved in order to establish a stronghold in northern Jutland to counter the ongoing rebellions by the local nobility and peasants against the crown. The castle was successful and from the 15th century and onwards the castle had a more peaceful role as the local administrative center. King Christian II held the future Swedish king Gustav Vasa captive at Kalø during 1518-1519, until he escaped.
When king Frederick III converted the elective monarchy into an absolute monarchy by the revolution of 1660 in Denmark, the castle lost its function. In 1661, Frederick III gave Kalø to Ulrik Frederik Gyldenløve, who in the following year (1662), tore down the now abandoned castle. The material was used to build his private palace in Copenhagen, now called the Charlottenborg Palace. Today the castle ruin is owned by the Danish State.

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
