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:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
