The Museo Arqueológico Municipal de Jerez de la Frontera is an archaeological museum established in 1873 as the Municipal Archaeological Collection, merging collections donated by wealthy individuals, and based at the Old City Hall of Jerez de la Frontera. The museum opened to the public in 1935. The collection includes a Corinthian helmet, extremely rare in Spain, found near the city's Charterhouse by the river Guadalete. The collection also includes Roman ceramics and other items.
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.
