The Château du Hohlandsbourg is a ruined castle Wintzenheim, near Colmar. The construction of the castle, on the order of the Provost of Colmar, Siegfried de Gundolsheim, dates from 1279. The site, 620 m above sea level, allowed for surveillance of Colmar and its region. In 1281, the townspeople of Colmar revolted and set fire to the castle with the help of the Bailiff, Otton d'Ochenstein.
The castle came under the control of the Ensisheims before being given in 1410 as a fiefdom to the Ribeaupierres, then Counts of Lupfen, who enlarged it. In the 16th century, the castle belonged to Lazarus von Schwendi, general of the Holy Roman Empire, who, it is said, brought Tokay vines from Hungary to Alsace. He enlarged and strengthened the castle.
With Alsace becoming French at the end of the Thirty Years' War, the castle welcomed troops who blew it up in 1637 to prevent it falling into the hands of an Austrian army.
Today Hohlandsbourg Castle offers a magnificent all-round panorama over the plain of Alsace and the Vosges Mountains. It is open to in summer season.
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.
