Capriccio
In painting, a capriccio (Italian pronunciation: [kaˈprittʃo], plural: capricci [kaˈprittʃi]; in older English works often anglicized as "caprice"), means especially an architectural fantasy, placing together buildings, archaeological remains and other architectural elements in fictional and often fantastical combinations, perhaps with staffage of figures. It fits under the more general term of landscape painting. It may also be used of other types of work with an element of fantasy. (sourse: en.wikipedia.org)
