Arechi Castle is a castle in southern Italy located on top of a mountain, at the foot of which lies the city of Salerno.
The construction of the castle began in the 6th century under the Byzantine rule (the construction of the oldest part of the ramparts made of sandstone blocks is characteristic of this period).
Salerno was part of the Duchy of Benevento, which was the southernmost part of the Kingdom of the Lombards. When Charlemagne attacked the Lombards in the year 774, the Duchy of Benevento was ruled by Arechi II. He moved the main centre of power from Benevento to Salerno in order to strengthen his control over strategic areas such as the coastline and to secure communications within the province of Campania. During this period the castle was heavily fortified and its ramparts took the shape that have survived to our times.
Over the centuries, the castle had many owners. Archaeological work has identified, among other things, traces of the Norman presence. A watchtower was built north of the castle, allowing to conduct observations of the Gulf of Salerno.
Currently, the castle has been bought from the commune by a private company that arranged a restaurant inside. The defensive walls, however, are open to visitors free of charge, there is also a museum in the castle (large collections of coins and medieval ceramics were found during the renovation). At night, perfectly lit, it is visible from almost anywhere in Salerno.
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.
