Borum Eshøj is one of the largest Bronze Age mound sites in Denmark. Three graves were found from there dating back to about 1350 BC. The bodies lay in their coffins of hollowed out oak tree trunks in graves that are among the most important prehistoric finds. The oak coffin graves were excavated in the 1870s and are now on show at the National Museum of Denmark. The areas once had more than 40 barrows but most have now gone. The remains of Borum Eshøj are still visible, and recently Moesgård Museum excavated and reconstructed three more of the barrows. A copy of a Bronze Age house has also been built.
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.
