A palace is a large residence, often serving as a royal residence or the home for a head of state or another high-ranking dignitary, such as a bishop or archbishop. The cited article says the word is derived from the Latin palatium, for the Palatine Hill in Rome, which housed the Imperial residences, and that most European languages have a version of the term, many using it to describe a broader 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, and it is also used for some large official buildings. Buildings recorded in the atlas as palaces are grouped under this concept.
