Villa Thiene is a 16th-century villa at Quinto Vicentino in the province of Vicenza. The building as it stands today is the work of several architects one of whom was Andrea Palladio. Like several other projects on which Palladio worked, it was commissioned by two brothers, in this case Marcantonio and Adriano Thiene. Since 1996, the villa has been conserved as part of a World Heritage Site, the "City of Vicenza and the Palladian Villas of the Veneto". The World Heritage Site also includes the Palazzo Thiene in the city of Vicenza which belonged to same Thiene brothers.
Palladio was involved with Villa Thiene in the 1540s, making it one of his earlier works. He appears to have adapted a design by Giulio Romano. The extent of Romano's involvement in the project is not clear, in any case he died in Mantua in 1546 while the villa was still under construction. One of the Thiene brothers, Adriano Thiene, had to flee Vicenza in 1547 and building work appears to have been put on hold at that time.
A version of the villa is illustrated and discussed in I Quattro Libri dell'Architettura of 1570. As with a number of the villas described in Palladio's publication, there are differences between what was published and what was actually built. Palladio's plan indicates that the present building was not intended for the mansion itself, but for one of the agricultural wings. However, there are sixteenth-century frescoes in the building by Giovanni de Mio, suggesting that it was decided at an early state that the building would not be purely utilitarian.
