The Villa Angarano was originally conceived by Andrea Palladio who published a plan in his book I Quattro Libri dell'Architettura. Work was started on the wings of Palladio's design in the 1540s or 1540s . A decision appears to have been reached to leave a pre-existing house in the middle of the site. The proposed Palladian villa was never built: Palladio's patron may have been obliged to halt the project for financial reasons. However, the central building was eventually rebuilt after a plan by Baldassarre Longhena, which is not Palladian in style.
The original design included areas to serve as cellars, stables, dove-houses, wineries, and other utilitarian spaces. However, not all of these features were actually built.
Although the building as it stands is only partly by Palladio, in 1996 UNESCO included it in the World Heritage Site 'City of Vicenza and the Palladian Villas of the Veneto'.
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.
