PAVILION  , properly a

tent, a late use of Lat. papilio, butterfly, from which the word is derived through the French . The term is chiefly used of a tent with a high pitched roof, a small detached building used as a summer-house, &c., and particularly for a building attached to a recreation ground for the use of players and members . In architecture the term pavilion is specifically applied to a portion of a building which projects from the sides or central part . It is a characteristic of French renaissance architecture . Where the buildings of a large institution are broken up into detached portions, as in St Thomas's Hospital, London, the term is generally applied to such detached buildings .
