[1] The estate dates back to the Middle Ages, when it was an ecclesiastical property known as Hjortholm within the Ancient Diocese of Roskilde.
The king put an end to the industrial works on the property, as he had plans to build a large maison de plaisance on the grounds for use as a summer residence.
Charlotte Amalie reinitiated the industrial production of the estate and expanded its output with the construction of a paper mill.
[1] Frederick IV ceded the estate to his sister, Princess Sophia Hedwig, who began the construction of a house on the land which for unknown reasons bore a striking resemblance with Ørholm Manor on the island of Funen, but it was never completed.
[3] The town of Bagsværd was separated from the Frederiksdal estate in 1735, and in 1739 Frederiksdal was put at the disposal of Johan Sigismund Schulin (1694–1750), a close friend of the royal family who had been ennobled by the crown in 1731 and received a number of prominent appointments since Christian VI's ascension to the throne in 1730.
The estate was therefore managed by his mother, Catarine Marie Schulin (née von Møsting), who carried out alterations on the building in 1752 and 1753 with the assistance of the architect Johann Gottfried Rosenberg.
Within a few years of taking charge of the estate from his mother, he was on the verge of bankruptcy, and had been ordered by the supreme court to pay off his debts.
Like his father before him, he was only three years old when he unexpectedly inherited the estate, and so it was managed by his mother Sophie Hedevig until her death in 1807.
Frederiksdal is credited with being the earliest example of a maison de plaisance in Denmark and the building is today protected.
The interior features a combination of large and small rooms symmetrically arranged around the main axis' vestibule and conservatory.
There are rich Rococo stucco decorations, particularly in the Garden Hall, executed by Carlo Enrico Brenno and Giovanni-Battista Fossati.
[citation needed] The hilly landscape of Frederiksdal was created by meltwater erosion from the last ice age.
More than 171 bird species have been recorded within the estate, including: great spotted woodpecker, little grebe, goldeneye, moorhen, northern lapwing, little ringed plover, european honey buzzard, rough-legged buzzard, osprey, wood sandpiper, green sandpiper, chaffinch, brambling, grey heron.
