A palace is a grand residence, especially a royal residence, or the home of a head of state or some other high-ranking dignitary, such as a bishop or archbishop. The word is derived from the Latin name palātium, for Palatine Hill in Rome which housed the Imperial residences. Most European languages have a version of the term (palais, palazzo, palacio, etc.), and many use it for a wider range of buildings than English. In many parts of Europe, the equivalent term is also applied to large private houses in cities, especially of the aristocracy; often the term for a large country house is different. Many historic palaces are now put to other uses such as parliaments, museums, hotels, or office buildings. The word is also sometimes used to describe a lavishly ornate building used for public entertainment or exhibitions such as a movie palace. A palace is distinguished from a castle while the latter clearly is fortified or has the style of a fortification, whereas a palace does not. Etymology The word palace comes from Old French palais (imperial residence), from Latin Palātium, the name of one of the seven hills of Rome. The original "palaces" on the Palatine Hill were the seat of the imperial power while the "capitol" on the Capitoline Hill was the religious nucleus of Rome. Long after the city grew to the seven hills the Palatine remained a desirable residential area. Emperor Caesar Augustus lived there in a purposely modest house only set apart from his neighbours by the two laurel trees planted to flank the front door as a sign of triumph granted by the Senate. His descendants, especially Nero with his "Domus Aurea" (the Golden House), enlarged the building and its grounds over and over until it took up the hill top. The word Palātium came to mean the residence of the emperor rather than the neighbourhood on top of the hill. Palace meaning "government" can be recognized in a remark of Paul the Deacon, writing c. AD 790 and describing events of the 660s: "When Grimuald set out for Beneventum, he entrusted his palace to Lupus" (Historia Langobardorum, V.xvii). At the same time, Charlemagne was consciously reviving the Roman expression in his "palace" at Aachen, of which only his chapel remains. In the 9th century, the "palace" indicated the housing of the government too, and the constantly travelling Charlemagne built fourteen. In
