Betnava estate was first mentioned in 1319, under the name Wintenaw. By the 16th century, it had grown into a fortified and moated renaissance manor.
It passed through the hands of numerous owners, including the noble families of Herberstein, Khiessl, Auersperg, Ursini-Rosenberg, Szekely, Brandis in von der Dur. During their tenure, the counts Herberstein transformed it into a Protestant way-station, complete with chapel and cemetery. In 1863, Betnava became the summer residence of the bishops of Maribor and Lavant, having already been leased by the see for several decades.
In 1784, the mansion was rebuilt in late-baroque Florentine style, after the fashion of Vienna at the time. The west wing contains a chapel dedicated to the Holy Cross, while other notable features include a carved staircase leading to the main hall, itself decorated with late-baroque trompe l'oeil ceiling frescoes painted by an unknown artist c. 1780.
The main facade faces a 19th-century English country park.
The mansion's current owner is the archbishpric of Maribor, which was in 2011 cited by the Agency for the Protection of Cultural Heritage for failure to properly maintain the site and safeguard structures uncovered in an archeological dig.
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.
