The Villa Wartholz is a former imperial villa in Reichenau an der Rax. Villa Wartholz was designed by Heinrich von Ferstel in the historicist style in the years 1870 to 1872 for Archduke Karl Ludwig of Austria. The castle-like building with towers was for recreational purposes, not for military means. The villa was designed with a view over the valley. Karl Ludwig spent so much time in this area, he reserved this place only for hunting by the imperial court. It was built near by his home Karl-Ludwig-Haus on the Rax.
This area around Reichenau was a popular tourist area for the aristocratic society since the construction of the Southern Railway. Members of the imperial family, and other members of the nobility, artists and scientists met at the Villa Wartholz. Nearby another palace subsequently arose, the Schloss Rothschild.
The villa also was used by Emperor Charles I of Austria and Empress Zita. Their son, Otto von Habsburg (1912 – 2011) was born in Villa Wartholz. His baptism and first Communion were received in the chapel, which was located in the villa. On 17 August 1917, Otto von Habsburg held a ceremony where he handed over the Military Order of Maria Theresa to 24 officers, among them Kövess, Dankl, Arz, Wenzel von Wurm, Cavallar and Banfield.
Due to the Habsburg Law the Wartholz villa was owned by the Austrian state. The Habsburgs staked a claim of private ownership and for many years this was a point of contention whether they would be reinstituted as owners. In 1973, the government sold the mansion to the State of Lower Austria. From this it was again sold in 1982 and is now privately owned.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
