Hohenstaufen Castle was seat of the now-defunct House of Hohenstaufen. The castle was built around 1070 by Frederick I of Hohenstaufen (even before he became Duke of Swabia), as a fortress to protect family interests in the vicinity. Until the 13th century, the castle was a possession of the imperial and royal family, the Hohenstaufen dynasty. In 1181, Emperor Frederick Barbarossa stayed there; in 1208, Irene Angelina, the widow of Barbarossa"s son, the recently murdered Philip of Swabia, died at Hohenstaufen Castle.
After the fall of the Hohenstaufen in 1268, the castle was declared an imperial possession by the Habsburg king Rudolf I of Germany. The strategically and symbolically important location was a constant bone of contention between the Counts of Württemberg and the Holy Roman Emperor.
In 1372, Hohenstaufen Castle finally was in the hands of the Württemberg rulers. After the expulsion of Duke Ulrich of Württemberg by the members of the Swabian League in 1519, one Georg Staufer of Bloßenstaufen successfully claimed the castle, as a descendant of the old Hohenstaufen dynasty. Therefore, only a small force defended the castle in 1525, when it was taken and destroyed by insurgents during the German Peasants" War. Stones from the castle were later used in the construction of the Renaissance Göppingen Castle.
Since the German unification of 1871, Hohenstaufen Castle has been regarded as a national monument. The archaeologist Walther Veeck undertook excavations on it between 1936 and 1938, and further excavations were made between 1967 and 1971, uncovering and securing the castle foundations. A Hohenstaufen memorial stele was inaugurated in 2002. In 2009 additional work was done to preserve the site.
The Staufer Museum, located at the intersection of Pfarrgasse and Kaiserbergsteige in Hohenstaufen, contains artifacts from and historical information about the site. The trail that leads to the castle site starts between the two churches that are adjacent to the Staufer Museum.
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.
