Forte Sperone is the heart of Genoa's 19th-century fortifications, located right at the apex of the 'Mura Nuove' (new walls) from 1630, which to this day take the shape of mighty ramparts nestled in the hills behind the city centre.The fort's main entrance, with the Savoy coat of arms above it, is protected by a moat and a heavy gate that was once connected to a drawbridge via two chains; other important architectural elements include a well-preserved gunpowder magazine, located in the lower part of the fort, central barracks with large rooms, and a beautiful little chapel attached to the complex.
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.
