Between 1993 and 1996, several archaeological excavation campaigns at the site of Las Eretas partially unearthed the urban fabric of a fortified village from the Early Iron Age, the most significant structural remains of which included the wall and towers that defended it, and several dwellings built around a street and public square which facilitated pedestrian traffic inside the fortress.
The protohistoric village with its houses dates from the 6th to the 4th centuries BC and are typical of the Urnfield culture. Today there is a museum where thematic areas have brief text with illustrations – maps, photographs and drawings –, and a display cases showing original archaeological pieces, both from the Las Eretas site and other Navarrese Iron Age villages which have been investigated.
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.
