The Villa Angarano was originally conceived by Andrea Palladio who published a plan in his book I Quattro Libri dell'Architettura. Work was started on the wings of Palladio's design in the 1540s or 1540s . A decision appears to have been reached to leave a pre-existing house in the middle of the site. The proposed Palladian villa was never built: Palladio's patron may have been obliged to halt the project for financial reasons. However, the central building was eventually rebuilt after a plan by Baldassarre Longhena, which is not Palladian in style.
The original design included areas to serve as cellars, stables, dove-houses, wineries, and other utilitarian spaces. However, not all of these features were actually built.
Although the building as it stands is only partly by Palladio, in 1996 UNESCO included it in the World Heritage Site 'City of Vicenza and the Palladian Villas of the Veneto'.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
