The Mausoleum of Augustus is a large tomb built by the Roman Emperor Augustus in 28 BC. The interior of the mausoleum is not open to tourists. The mausoleum was one of the first projects initiated by Augustus in the City of Rome following his victory at the Battle of Actium in 31 BC. The mausoleum was circular in plan, consisting of several concentric rings of earth and brick, planted with cypresses on top of the building and capped by a conical roof and a statue of Augustus. Vaults held up the roof and opened up the burial spaces below.
In the Middle Ages the tumulus was fortified as a castle and occupied by the Colonna family. After the disastrous defeat of the Commune of Rome at the hands of the Count of Tusculum in 1167, the Colonna were disgraced and banished, and their fortification in the Campo was dismantled. Thus it became a ruin.
It was not until the 1930s that the site was opened as a preserved archaeological landmark along with the newly moved and reconstructed Ara Pacis nearby. The restoration of the Mausoleum of Augustus to a place of prominence featured in Benito Mussolini's ambitious reordering of the city of Rome which strove to connect the aspirations of Italian Fascism with the former glories of the Roman Empire.
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.
