St. Lambrecht's Abbey was founded in 1076 by Count Markward of Eppenstein; it was dissolved from 1786 to 1805. In 1938, the building was seized by the National Socialists. From 1942 to 1945, it was used as an external storage facility of the Mauthausen-Gusen concentration camp. The monks returned in 1946.
Locally the two churches within the monastic grounds are called the Grosskirche ('big church') and the Kleinkirche ('little church'). During restoration work of the Grosskirche in the early 1970s extraordinary frescoes dating from the latter half of the 15th century were discovered on the north wall. These show the throne of Solomon.
On the lowest level is depicted the Old Testament Judgment of Solomon, above this the Virgin Mary with the baby Jesus, and above all else Jesus Christ: 'the Word of God made Flesh'. Other frescoes dating from the 14th century depict Saint Christopher and Saint Agnes. Formerly in the monastery there was also a votive altarpiece from which the Master of the Saint Lambrecht Votive Altarpiece received his name; this is now in the Alte Galerie in Graz.

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.
