Villa Chiericati was designed for Giovanni Chiericati by the architect Andrea Palladio in the early 1550s. In 1996 UNESCO included the villa in the World Heritage Site City of Vicenza and the Palladian Villas of the Veneto.
The villa is square and a portico projects from its principal facade. The principal rooms are built upon a piano nobile above a semi-basement. The upper floor is very much of secondary importance. The design of the villa was to be the prototype for Palladio's later works at the Villa Rotonda and the Villa Malcontenta.
Work on the villa stopped after the death of Palladio's client. It was not finally completed until after it had been purchased by Ludovico Porto in 1574. In 1584 he employed the architect Domenico Groppino, who had collaborated with Palladio on other projects, to complete the villa.There is some debate as to the extent Groppino influenced the eventual design of the building. While the portico is undoubtedly by the hand of Palladio himself, the position of the windows is at variance with the architect's own advice in I Quattro Libri dell'Architettura, where he warns against placing windows near the corner of a building lest it weaken the structure (the villa does in fact reveal signs of settlement here).
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.
