Mõdriku estate (Mödders) was first mentioned in 1470. Over the centuries, it has been the property of various Baltic German families. During the 20th century, it has been used by various schools. The building traces its oldest parts to the 17th century, but has been extensively enlarged and rebuilt both during the 1780's and 1890's.
The manor was the home of several successive generations of the von Kaulbars family, including Russian general and explorer Alexander Kaulbars. An ancestor to him, R. A. von Kaulbars (reputedly a great patriot) put up the column commemorating the French-Russian War of 1812 that is still visible in the manor park.
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.
