A pergola is a garden feature forming a shaded walk or passageway of pillars that support cross beams and a sturdy open lattice, upon which woody vines are trained. It may also be part of a builiding, as protection for an open terrace. The origin of the word is the Late Latin pergula, referring to a projecting eave. The term was borrowed for English from Italian, mentioned in an Italian context in 1645 and used in an English context in 1675,
Pergolas may link pavilions, may extend from a building's door to an open garden feature such as an isolated terrace or pool, or may be entirely free-standing structures shading a length of walkway.
