Villa Porto was designed in 1554 and traditionally attributed to the Italian architect Andrea Palladio, but not included by UNESCO in the strict list of Palladian Villas of Veneto
In 1554, Paolo Porto and his brothers divided up their father’s inheritance, Paolo acquiring an estate at Vivaro, north of Vicenza. Here, during the subsequent four years, he realised a villa which tradition holds was designed by Palladio. The Conte Paolo Porto, one of the most powerful canons of the Cathedral (in 1550 he was on the point of becoming bishop) was a sophisticated and cultured man, who passed much time in Rome where he could count on the friendship of Cardinal Alessandro Farnese. Porto also numbered among his Vicentine friends and relatives Palladio’s foremost patrons, men like Giangiorgio Trissino, Biagio Saraceno, Bernardo Schio, and Girolamo Garzadori.
It is perhaps this network of friendships which most easily placed him in contact with Palladio, although in this regard careful inspection of the villa’s architecture raises more doubts than certainties. For one discerns various successive constructional phases, which render the identification of an original Palladian scheme, if any, most difficult. The pronaos, for example, is grafted onto the main block with manifest discontinuity. Moreover, the two lateral wings are without doubt nineteenth-century, and actually the product of a belated “Palladianization” of the villa at the hands of the architect Antonio Caregaro Negrin.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
