The Hôtel van Eetvelde is a town house designed in 1895 by Victor Horta for Edmond van Eetvelde, administrator of Congo Free State. Together with the Hôtel Tassel, the Hôtel Solvay and his own House and atelier it was put on the "UNESCO World Heritage List" in 2000 as the core of epoch-making urban residences Victor Horta designed before 1900.
The visible application of 'industrial' materials such as steel and glass was a novel for prestigious private dwellings at the time. In the Hôtel van Eetvelde Horta also used a hanging steel construction for the façade. The interior receives additional lighting through a central reception room covered by a stained-glass cupola. An extension to the house was designed by Horta in 1898. This building has a more conventional, beautifully detailed sandstone façade. It was designed to house a garage, an office for van Eetvelde as well as supporting apartments and therefore had a separate entrance.
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.
