Gustavianum is the former main building of Uppsala University, built 1622–1625 and named after King Gustavus Adolphus. Under the cupola is the theatrum anatomicum, the second oldest in the world added to the building in the mid 17th century by Olaus Rudbeck, professor of medicine and amateur architect, among other things.
Although still used for lectures and conferences, most of Gustavianum functions as a museum, including exhibitions of objects from the university collections of Classical, Egyptian and Nordic antiquities, as well as an exhibition on the history of science and the history of Uppsala University. The Augsburg art cabinet, the best preserved of the Kunstschränke made by Philipp Hainhofer, which was given to Gustavus Adolphus in 1632 by the City of Augsburg, is on display in the Gustavianum.
The Museum has an excellent science collection of very old telescopes of Celsius and other astronomers, the oldest achromatic telescope, a book with Copernicus notes on solar eclipses, an important Lineus exhibition and currently an exhibition of the oldest known astronomical instrument and computer, the Antikythera Mechanism.
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.
