The idea and function of a villa has evolved considerably since its invention towards the end of the Roman Republic.
Roman writers refer with satisfaction to the self-sufficiency of their villas, where they drank their own wine and pressed their own oil, a symptom of the increasing economic fragmentation of the Roman empire. When complete working villas were donated to the Christian church, they served as the basis for monasteries that survived the disruptions of the Gothic War and the Lombards. An outstanding example of such a villa-turned-monastery was Monte Cassino.
Numerous Roman villas have been meticulously examined in England. Like their Italian counterparts, they were complete working agrarian societies of fields and vinyards, perhaps even tileworks or quarries, ranged round a high-status power center with its baths and gardens. The grand villa at Woodchester preserved its mosaic floors when the Anglo-Saxon parish church was built (not by chance) upon its site. Burials in the churchyard as late as the 18th century had to be punched through the intact mosaic floors. The even more palatial villa rustica at Fishbourne near Winchester was built uncharacteristically as a large open rectangle with porticos enclosing gardens that was entered through a portico. Towards the end of the 3rd century, Roman towns in Britain ceased to expand: like patricians near the center of the empire, Roman Britons withdrew from the cities to their villas, which entered on a palatial building phase, a "golden age" of villa life.
Two kinds of villa plan in Roman Britain may be characteristic of Roman villas in general. The more usual plan extended wings of rooms all opening onto a linking portico, which might be extended at right angles, even to enclose a courtyard. The other kind featured an aisled central hall like a basilica, suggesting the villa owner's magisterial role. The villa buildings were often independent structures linked by their enclosed courtyards. Timber-framed construction, carefully fitted with mortices and tenons and dowelled together, set on stone footings, were the rule, replaced by stone buildings for the important ceremonial rooms. Traces of window glass have been found as well as ironwork window grilles.
In Spain, a villa is a town with a charter (fuero) of lesser importance than a ciudad ("city"). Later evolution has made the distinction between villas and ciudades a purely honorific one. Madrid is the Villa y Corte, but the much smaller Ciudad Real was declared ciudad by the Spanish crown. Villa (or its cognates) is part of many Spanish placenames, like Vila Real and Villadiego. When it is associated to a person name, it was probably used in the original sense of a country estate rather than a chartered town.
Rome had more than its share of villas with easy reach of the small 16th century city:Villa Madama, the design of which, attributed to Raphael, was carried out by Giulio Romano in 1520, was one of the most influential private houses ever built; elements derived from Villa Madama appeared in villas through the 19th century. Villa Albani was built near the Porta Salaria. Other are Villa Borghese with its famous gardens; the Villa Doria Pamphili (1650); the Villa Giulia of Pope Julius III (1550), designed by Vignola.
The cool hills of Frascati gained the Villa Aldobrandini (1592); the Villa Falconieri and the Villa Mondragone.
The Villa d'Este near Tivoli is famous for the water play in its terraced gardens. The Villa Medici was on the edge of Rome, on the Pincian Hill, when it was built in 1540.
The following English houses were conceived originally as "villas" in the 18th-century sense:
The contemporary architecture however has some important examples of buildings called "villas":
