It is first recorded in a letter from 1186 where Pope Urban III thinks Bishop Absalon for giving it to Roskilde bishopric.

The area was administrated from Hjortholm Castle at Furesøen in Frederiksdal After the Reformation, when the Crown confiscated all land owned by the Church, Høsterkøb came under the Hørsholm Estate.

The largest property in Høsterkøb is Friheden, which stands on 30 hectares (74 acres) of land on the northeastern outskirts of the village.

On the other side of the street, the Catholic church also owns Meglås, a former country house now operated as an educational centre.

The house is from 1910 and was built by Aage Westenholtz, Karen Blixen's uncle, who supported her economically when her African farm faced bankruptcy.
