The history of Venngarn manor dates to the 12th century. After several owners it was acquired by crown in 1555. Gustav II Adolphus donated Venngarn to Franz von Thurn Berendt and his son sold it to Magnus Gabriel De la Gardie in 1653. The late 17th century was a golden age for Venngarn castle. The present castle was built mainly in 1670 by the architect Jean de la Vallée.
As a chancellor and the leader in Charles XI's regency, De la Gardie was Sweden's most important politicians. Unfortunately for him, due the king's reduction De la Gardie had to return Venngarn later to the crown. Since 1686 the state of Sweden has leased Venngarn castle for several families and purposes. In 1916 a central government institution for alcoholism treatment was established at Venngarn. In 1997 it was sold to its current owners, Wenngarn AB.
There is also a notable chapel in the castle. When the crown took Venngarn 1686, the chapel was completely untouched. None have been added and only a few details have been lost since then. Thus, the chapel one of the country's best preserved church from the Age of Greatness. It was prepared by the De la Gardie, and presumably he also has hired Jean de la Vallee as an architect.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
