The Treasury of Atreus or Tomb of Agamemnon is a large tholos or beehive tomb constructed between 1300 and 1250 BCE in Mycenae, Greece.
It is the largest and most elaborate tholos tomb known to have been constructed in the Aegean Bronze Age, and one of the last to have been built in the Argolid. The main tomb consisted of a circular burial chamber, or thalamos, topped with a corbelled dome. This dome was the largest in the world until the Roman period, and remains the world's largest corbelled dome. Originally, the façade was decorated with marble columns and sculptures, which used marble from the Mani Peninsula in the southern Peloponnese. Its artwork has been suggested to have been inspired by that of Minoan Crete and of Ancient Egypt.
Little is known of the persons who might have been buried in the tomb: the identification with the mythical Atreus and Agamemnon likely dates to the 18th century. The immense labour involved in the construction of the tomb, as well as the similarities between the architecture of the tholos and the structures of the citadel of Mycenae, has led to suggestions that it may have been intended for a ruler of Mycenae, and represent Mycenae's increasingly dominant status in the later part of the Bronze Age.
The tomb was first excavated in the 19th century, when parts of the marble sculptures of its façade were removed by the British aristocrat Thomas Bruce, 7th Earl of Elgin and the Ottoman governor Veli Pasha. It was partly excavated by Heinrich Schliemann, and more fully by Panagiotis Stamatakis, in the 1870s. Throughout the 20th century, the British School at Athens made a series of excavations in and around the tomb, led by Alan Wace, which primarily aimed to settle the difficult question of the date of its construction.
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.
